Unit 1 enzymes i think Flashcards
What type of energy do all cells use?
Chemical energy
What is metabolism?
Metabolism is a chemical process that is necessary to maintain life.
What does metabolism include?
Catabolism and Anabolism
What is catabolism?
The breakdown of larger molecules
What is anabolism?
The synthesis (combination) of smaller molecules
What is a catalyst?
A catalyst is a substance that increases the rate of reaction and they do not change in the process and is reusable.
What is the name of a biocatalyst in this chapter?
Enzyme
Why are enzymes called biocatalysts?
Because
- they are typically derived from plants, micro-organism, or animal tissue
- They can catalyse almost all biochemical reactions in living cells
The 2 functions of catalyst:
- TO speed up reaction rate without being used up in the reaction
- Control all chemical reactions so that they happen at the best rate
Maltose, sucrose, lactose, protein, lipids, amylose
These are all names of (substrate/enzyme)
substrate
Maltase, sucrase, lactase, protease, lipase, amylase
These are all names of (substrate/enzyme)
enzyme
What is denaturation? what are the causes? is it reversible?
When the shape of the active site changes, as a result of high temperatures or PH, It is irreversible
At what temperature are enzymes most active?
37ºC
Why are enzyme efficient?
It’s because they can be reused again and again. Only a small amount is needed to catalyse the reactions.
Why are enzymes specific?
It is specific because it only interacts with one specific substrate to form an enzyme-substrate complex.
