DNA.
4 of 20
What are the four base pairings? (and their complementary pairings)
A and T. C and G.
5 of 20
What does each gene contain?
A different sequence of bases.
6 of 20
How is each amino acid coded for?
By a sequence of 3 bases.
7 of 20
What does each gene code for?
A particular protein
8 of 20
What is the purpose of the genetic code?
To control cell activity, therefore affects some characteristics of the organism.
9 of 20
What are enzymes?
Biological catalysts that speed up chemical reactions in living cells.
10 of 20
What is denaturing?
An irreversible change that changes the shape of the active site and inhibits enzyme function.
11 of 20
Give the equation to work out Q10 value.
Rate at higher temperature / rate at lower temperature

What are mutations?
Changes to genes that may lead to the production of different proteins.
13 of 20
Name 2 ways that mutations can occur.
Spontaneously and by radiation/chemicals.
14 of 20
Give the word equation for aerobic respiration.
Glucose + oxygen --> carbon dioxide + water
15 of 20
What is ATP used for?
As an energy source for many processes in the cell.

Give the word equation for anaerobic respiration.
Glucose --> lactic acid
18 of 20
Give two effects of lactic acid.
It accumulates in the muscles, causing pain and fatigue.
