Ka2 Cellular Respiration

Question 1

What is phosphorylation

Answer 1

When molecules have a phosphate added to them so become energy rich

Question 2

What is ATP used for

Answer 2

To transfer and provide energy to provide pathways and other cellular processes

Question 3

What are the 3 stages

Answer 3

Glycolysis
Citrix acid cycle
Electron transport chain

Question 4

What is glycolysis

Answer 4

The breakdown of glucose ro pyruvate
Does not require energy

Question 5

Where does glycolysis occur

Answer 5

Cytoplasm

Question 6

What is the fate of products in glycolysis

Answer 6

Pyruvate molecules enter stage 2
ATP can be used in other cellular processes
NASH goes to stage 3

Question 7

Where does the citric acid cycle occur

Answer 7

Central matrix of the mitochondria

Question 8

What is anaerobic respiration

Answer 8

Called fermentation
When oxygen is unavailable stage 2 and 3 cannot work

Question 9

What happens if oxygen is absent

Answer 9

Animal cells
- glycolysis -> pyruvate <> locate acid

Plant/yeast cell
- glycolysis-> pyruvate <> ethonal + co2

Question 10

Where does the electron transport chain occur

Answer 10

Inner membrane of the mitochondria
