After vigorous exercise, breathing rate stays high to:
Cool the lungs
Remove glucose
Make lactic acid
Repay the oxygen debt
14.
This reaction is performed to recycle NAD+ needed for efficient respiration.
This reaction is performed to recycle NAD+ needed for efficient respiration.
Glycolysis
Krebs cycle
Oxidative phosphorylation
Lactic acid fermentation
Chemiosmosis
15.
When oxygen becomes unavailable, this process regenerates NAD+, allowing respiration to continue.

16.
What is produced in anaerobic respiration in yeast?
Ethanol and CO2
Lactate only
Lactate and CO2
Ethanol and water
17.
What is the main purpose of converting pyruvate to lactate?
To make extra ATP
To regenerate NAD for glycolysis
To produce CO2
To store energy as glycogen
18.
Which statement best describes Anaerobic respiration?
The product of anaerobic respiration in mammals, formed when pyruvate is reduced by reduced NAD.
Respiration without oxygen, in which only glycolysis produces ATP and NAD is regenerated by reducing pyruvate.
Oxygen, which accepts electrons and protons at the end of the ETC to form water.
A series of electron carrier proteins in the inner mitochondrial membrane that pass electrons along in redox reactions.
