1

What is ATP formed from?

ADP + phosphate ion

2

What happens in glycolysis?

- no oxygen needed
- in cytoplasm
- glucose ( 6 carbon) split to 2 3 carbon molecules, which are converted to pyruvate ions
- atp produced

3

What happens in anaerobic respiration Im muscle tissue?

Pyruvate—-> lactate and a small amount of ATP

4

What happens in fermentation?

Yeast respite anaerobically. Glucose —-> ethanol + CO2 and ATP

5

What happens in aerobic respiration?

In the presence of oxygen, sugar is completely oxidised in the mitochondria.
Glucose —-> CO2 + H2O + ATP (38)

6

What is photosynthesis?

Energy from sunlight used to produce chemical energy for life processes

7

What is the reaction in photosynthesis?

Carbon dioxide + water + light energy——> sugars and oxygen

8

What happens in photolysis?

-Water is split using light energy
- oxygen is released and hydrogen is retained on a hydrogen acceptor
-ATP is generated from ATP and phosphate

9

What happens in the second stage of photosynthesis?

- CO2 is fixed to make 2 sugars
- ATP needed

10

What light does chlorophyll absorb?

Blue and red might

11

Which type of light gives the largest amount of photosynthesis?

Blue and red lighted

12

What are limiting factors of photosynthesis?

Temperature, light intensity and CO2
