Cell Biology - Respiration

Question 1

Respiration

Answer 1

respiration is the release of energy from glucose in the presence of oxygen

Question 2

Fermentation

animals

Answer 2

Breakdown of glucose to pyruvate, then lactate when no oxygen is present

reversible

Question 3

Fermentation

plants

Answer 3

breakdown of glucose to pyruvate, then into carbon dioxide and ethanol

irreversible

Question 4

Respiration

word equation

Answer 4

glucose + oxygen –> energy (ATP) + carbon dioxide + water

Question 5

ATP

Answer 5

adenosine triphosphate is a high energy compound

when one of the bonds are broken energy is released and ADP + Pi is made

Question 6

lactate

Answer 6

chemical formed during fermentation in animal cells. when oxygen becomes present it can be converted back into pyruvate

Question 7

pyruvate

Answer 7

chemical formed from the splitting of a molecule of glucose during the first stage of respiration

Question 8

respirometer

Answer 8

a peice of equipment designed to measure the rate of respiration
