What is the energy in glucose used to regenerate

ATP

1

What can ATP be used for?

To transfer chemical energy to cellular processes

2

What is ATP generated from

ADP and Pi

3

Where does respiration occur

The cytoplasm and mitochondria

4

What are the three stages of respiration?

Stage 1- glycolysis
Stage 2 - the kerbs cycle
Stage 3 - the cytochrome system

5

Where does glycolysis happen

In the cytoplasm

6

What does glycolysis not require

Oxygen

7

What happens in glycolysis

6-carbon sugar glucose to two molecules of 3-carbon pyruvic acid

8

Haw many ATP are gained

2

9

What does glycolysis release

Hydrogen

10

What is the hydrogen carried away by

NAD as NADH

11

Where does the kerbs cycle happen

In the matrix of the mitochondria

12

What does the kerbs cycle require

Oxygen, it's aerobic

13

What happens in the kerbs cycle

2C acetyl group derived from pyruvic acid produced in glycolysis
The acetyl group joins with CoA acetyl-CoA
Acetyl-CoA reacts with a 4C compound to form a 6C compound citric acid
The citric acid is gradually converted back to the 4C compound. It's carbons are lost in carbon dioxide

14

Where does the cytochrome system occur?

The cristae of the mitochondria

15

What happens in the cytochrome system?

Hydrogen is passed through a series of carriers and finally combined with oxygen to form water.
Oxygen is the final hydrogen acceptor

16

How many ATP are produced

34 ATP
