Enzymes and Digestion: B1.2.1: AQA

The first spread on chapter 2 unit 1. Check my powerpoint here which is based on these Q&A type revision notes.

I use the power point to revise (I have a whiteboard, so do lots of brainstorming, etc) and then use the documents to test myself. They might be a bit useless on their own.

First 162 words of the document:

Enzymes and Digestion
1. What are the basic components of the human digestive system?
2. What are the structure and function of the major parts of the digestive system?
3. What is chemical breakdown and physical breakdown?
4. Why do we need more then 1 enzyme to break down molecules.
5. Why is the digestive system considered an interface?
6. What is assimilation?
7. What are the 3 general terms to describe the different enzymes that breakdown our food?
8. Suggest a reason why the stomach does not have villi or microvilli.
9. What part does the pancreas play in digestion?
Specification:
The gross structure of the human digestive system limited to oesophagus, stomach, small and large
intestines, and rectum. The glands associated with this system limited to the salivary glands and the
pancreas.
Digestion is the process in which large molecules are hydrolysed by enzymes to produce smaller
molecules that can be absorbed and assimilated

Here's a taster:

The human digestive system consisting of the long intestine muscle and it's glands that produce the
enzymes needed to help with digesting.
2. Oesophageous ­ Transports food from mouth to stomach. It is adapted for travel with its thick muscle
wall and not for digestion or absorption
It takes food from mouth to the stomach using waves of muscle contractions called peristalsis. Mucus is
secreted from tissues in the walls to lubricate the foods passage downwards.…read more
