12. Respiration

Question 1

The balanced symbol equation for respiration.

Answer 1

C 6 H 12 O 6 + 6 O 2 –> 6 CO 2 + 6 H 2 O + ATP

Question 2

define respiration.

Answer 2

the movement of oxygen from the outside environment to the cells within the tissues, and the transport of carbon dioxide in the opposite direction

Question 3

List the 4 stages in aerobic respiration

Answer 3

glycolysis
link reaction
krebs cycle
electron transport chain

Question 4

what is glycolysis, list the steps

Answer 4

The first stage of anaerobic and aerobic respiration.
It occurs in the cytoplasm and is an anaerobic process.
Glycolysis has the following steps…
- phosphorylation of glucose to glucose phosphate, using ATP
- production of triose phosphate
- oxidation of triose phosphate to pyruvate with a net gain of ATP and reduced NAD.

Question 5

what are the products of glycolysis?

Answer 5

net gain of 2 molecules of ATP
2 molecules of reduced NAD
2 molecules of pyruvate
