CB1e Enzymes and Nutrition Flashcards
How do digestive enzymes work in humans?
Digestive enzymes turn the large molecules in our food into smaller sub-units. This is then small enough to be digested by the small intestine.
What is protease?
An enzyme which breaks down protein molecules into amino acids
What is amylase?
An enzyme which breaks down starch molecules into glucose molecules
What is lipase?
An enzyme which breaks down lipid molecules into fatty acids and glycerol
What happens after the small molecules are absorbed into the body?
They can bused to build larger molecules that are needed in cells and tissues
What is the process of building larger molecules from smaller sub-units known as?
Synthesis
As complex carbohydrates and proteins are both made of small molecules or monomers in a chain, what can they be known as?
Polymers
What can reactions be sped up by?
Catalyst
What is a catalyst?
Something that speeds up an reaction without getting used up
Enzymes are B_______ C_______ that control reactions in the body
Biological Catalysts
What are biological catalysts?
They catalyse reactions that synthesise large molecules from smaller ones and breakdown large molecules into smaller ones
Enzymes speed up the rate of reaction but do not get used up int he reaction, true or false?
True
What are substrates?
The substance the enzyme works on
What are products?
The substance that are produced
