Unit 1 reparation

Question 1

Resperation

Answer 1

Chemical reaction stored in glucose being released by all cella through a series of enzyme controlled reactions
Begins in cytoplasm

Question 2

Resperation ATP

Answer 2

The energy released from the breakdown of glucose is to generate ATP.

The energy transferred by ATP can be used for cellular activities

Question 3

Cellular activities

Answer 3

Muscle cell contraction
Cell division
Protein synthesis
Transmission of nerve impulses

Question 4

Areobic reperation

Answer 4

Glucose is broken down to 2 molecules of pyravate, releasing enough energy to yeild 2 molecules of ATP

If oxegen is present aerobic Resperation takes place
Each pyravate is broken down to carbon dioxide + water
Releasing enough energy to yeild a large number ATP

Question 5

Word summery aerobic resperation

Answer 5

Glucose + oxegen ——> carbon dioxide + water + energy

Question 6

Fermentation pathway

Answer 6

Glucose is broken down to 2 molecules of pyravate , releasing enough energy to yeild 2 molecules of ATP
Absence of oxegen

Question 7

Fermentation in animals

Answer 7

The pyravate molecules are converted into lactate
Pyravate that breaks down
Glucose ——> lactate + energy

Question 8

Fermentation in plants

Answer 8

Yeast cell are converted into carbon dioxide and ethanol

Glucose ——> carbon dioxide + ethanol

Question 9

Where does fermentation take place

Answer 9

Cytoplasm

Question 10

Where does arrobic resperation take place

Answer 10

Mitochondria

Question 11

What is resperation controlled by

Answer 11

Enzymes
