For more information about enzymes see Enzymes. Enzymes, also known as "biological catalysts", are chemical elements that catalyze, and speed up the breakdown of complex food into simple nutrients. Here are a few and what they do:

Enzymes are sensitive. Each enzyme acts at a specific temperature, specific pH, and on a specific substrate (food upon which the enzymes act). For example, salivary amylase (found in the saliva of the mouth) works best at neutral pH, whereas gastric enzymes work best in acidic medium, and the intestinal or pancreatic enzymes work best in basic medium. The Optimum Temperature of enzymes is 37 &degrees;C, which is the normal human body temperature. The enzymes become inactive at 0 &degrees;C and are destroyed at 60 &degrees;C.

How to remember the enzymes in the digestive system?

I am doing access course in biology about the digestive system. I have an exam on the digestive system and enzyme

ScienceAid QnA. There are several ways you can remember the names of enzymes.

1) Sometimes, the name of the enzyme shows what substrate it acts on. For example, protease and peptidase digest proteins and peptides respectively. Whereas lipase digests lipids, and amylase acts on sugars.

2) In the digestive system, each enzyme is secreted and acts in a different medium. For example, pepsin (for proteins) is an enzyme that acts in acidic medium (therefore it should act in the stomach). Trypsin is an enzyme that acts in basic medium, therefore, it should act in the small intestine.

3) Third, by using logic. Remember, the sugar digestion starts in the mouth and continues in the small intestine, so the enzymes of the sugar molecules should be found in the mouth and the small intestine. The protein digestion starts in the stomach and continues to the small intestine, therefore, the proteases and the peptidases should be in the stomach and the small intestine. The lipid digestion starts in the small intestine, therefore lipases will be in the small intestine.

Thank you

How can I write an essay question on enzymes in digestion?

I have to write an essay for my college course on the digestive system can you help me?

ScienceAid QnA. We can give you hints and help you find the source. However, you have to read and write on your own.

For example, you can first define digestion, then in the body paragraphs, you can talk about the 2 types of digestion, and in each part mention where each type of digestion takes place and what are the enzymes involved. As a conclusion, you can talk about the different enzymes and how specific they are.

I am just reviewing the digestive system. Looking for information to help clarify peristaltic movement through longitudinal and circular muscles?

I really appreciate this website. I am enjoying reviewing the process of the digestive system. And I look forward sharing the site with my Biology students to also review over. I have not finished the article, I am looking for a website to help my students review information on the digestive system. I am trying to find two items in specific, list of enzymes that note where reactions occur and information on longitudinal/circular muscles.

I'm happy to hear that you are enjoying the site! Without know the age or level of your students, I'm not sure how accurate the information I've compiled for you is, BUT I was able to find some resources for you that I hope will help.

Name the enzymes that are found in the mouth: duodenum, and ileum?

I was given an assignment which is due tomorrow. I was asked to name the enzymes that are found in the digestive system. The answers that I want are not given.I really need these answers as it can broaden up my mind and help me to gain better understanding

The enzymes found in the mouth are:

  • Salivary Amylase.
  • Lysozyme.
  • Lingual Lipase.
  • Salivary Kallikrein.

6 21/04/20156 Outline I. Introduction Thesis: Ingestion, digestion, and absorption are the three major steps involved in the digestive process. II. Food is ingested. (T.S. - Ingestion, which occurs in the mouth, is the first step of the digestive process.) A. Food enters the mouth. B. Food is chewed. C. Food is ready to travel to the stomach. III. Food is digested. (T.S. - In the stomach, the second step of the digestive process begins.) A. Food is mixed with acidic gastric juices in the stomach. B. The partially liquid food moves from the stomach to the small intestine. C. Enzymes are secreted. IV. Absorption. (T.S. – The last step in the digestive process is absorption.) A. The digested food passes through the walls of the small intestine. B. The digested food is absorbed into the bloodstream. V. Conclusion Paraphrased Thesis: The digestion process involves three major steps: ingestion, digestion, and absorption.

7 21/04/20157 Introduction 1.State what the process is and why it is important.The digestive process is important in maintaining the lives of living organisms and in providing them with needed energy. 2.Give background information, and define the process.Groups of organs, such as the mouth, esophagus, stomach, and intestines, work together to perform this complex task. Digestion is the process of breaking down food from large molecules into small ones to make it easier for absorption. 3.State the thesis sentence to include the purpose and the main idea of the essay.The three major steps involved in the digestive process are ingestion, digestion, and absorption.

8 21/04/20158 Body Paragraphs  Topic sentence Ingestion, which occurs in the mouth, is the first step in the digestive process.  Major supporting sentence(s) After food enters the mouth, the teeth chew it. AND Saliva, which is produced by the salivary glands, plays a major role in breaking down the food into smaller pieces.  Minor supporting sentence(s) These small pieces travel to the stomach through the esophagus.

9 21/04/20159 Body Paragraphs When you write an essay body paragraph, you need to remember two points. First, each topic sentence must not only contain the main idea of the paragraph, but also that main idea must be a main point of the thesis sentence. Furthermore, the body paragraphs must be written in the order that the main points are listed in the thesis sentence. For example, if you write that the three major steps involved in the digestive process are ingestion, digestion, and absorption, then your first body paragraph must be about ingestion, the second about digestion, and the final body paragraph about absorption.

10 21/04/201510 Conclusion 1.Paraphrase the thesis sentence. 2.Summarize the main steps of the process. 3.Add no new information.

11 21/04/201511 The Essay - Introduction The digestive process is important in maintaining the lives of living organisms and in providing them with needed energy. Groups of organs, such as the mouth, esophagus, stomach, and intestines, work together to perform this complex task. Digestion is the process of breaking down food from large molecules into small ones to makeit easier for absorption. The three major steps involved in the digestive process are ingestion, digestion, and absorption.

12 21/04/201512 The Essay - DP1 Ingestion, which occurs in the mouth, is the first step of the digestive process. After food enters the mouth, the teeth chew it. Saliva, which is produced by the salivary glands, plays a major role in breaking down the food into smaller pieces. These small pieces travel to the stomach through the esophagus.

13 21/04/201513 The Essay - DP2 In the stomach, the second step of the digestive process begins. When the chewed food reaches the bottom of the esophagus, a valve lets the food enter the stomach. Contraction of the stomach wall mixes the food. Acidic gastric juices, which are secreted by the gastric glands in the stomach, help in mixing the food and in turning it into a partial liquid so it will have the ability to move into the small intestine. In the small intestine, enzymes are secreted, and digestion is completed.

14 21/04/201514 The Essay - DP3 The last step in the digestive process is absorption. Absorption takes place in the small intestine. The wall of the small intestine is lined with small, finger like projections called villi. Small molecules of food are absorbed by the huge number of villi. Some of these absorbed molecules enter the bloodstream to be distributed throughout the whole body.

15 21/04/201515 The Essay - Conclusion In conclusion, the digestive process involves three major steps: ingestion, digestion, and absorption. Ingestion, which occurs in the mouth, helps to increase the surface are of the food particles and prepares them for digestion. In the stomach, digestion begins, and it continues until it reaches the small intestine, where absorption takes place. The digestive process maintains organisms‘ lives by providing them with energy needed for different functions.
