respiration

Question 1

use of energy in living organisms

Answer 1

muscle contraction, protein synthesis,
cell division, active transport, growth, the
passage of nerve impulses and the maintenance of a constant body temperature

Question 2

what happens to yeast resipration when temp increase

Answer 2

increases until optimum then enzymes denature killing yeast

Question 3

aerobic resipration

Answer 3

chemical reactions in cells that use oxygen to break down nutrient molecules to release energy

Question 4

word equation aerobic resipration

Answer 4

glucose + oxygen → carbon dioxide + water

Question 5

chemical equation aerobic resipration

Answer 5

C6H12O6 + 6O2 → 6CO2 + 6H2O

Question 6

anaerobic resipration

Answer 6

chemical reactions in cells that break down nutrient molecules to release energy without using oxygen

Question 7

word equation anaerobic resipration in yeast

Answer 7

glucose → alcohol + carbon dioxide

Question 8

word eqaution anaerobic resipration in muscles

Answer 8

glucose → lactic acid

Question 9

chemical equation anaerobic resipration in yeast

Answer 9

C6H12O6 → 2C2H5OH + 2CO2

Question 10

what happens during vigurous exercise

Answer 10

State that lactic acid builds up in muscles and blood during vigorous exercise causing an oxygen debt

Question 11

what happens to fix oxygen dept

Answer 11

(a) continuation of fast heart rate to transport
lactic acid in the blood from the muscles to
the liver
(b) continuation of deeper and faster breathing
to supply oxygen for aerobic respiration of
lactic acid
(c) aerobic respiration of lactic acid in the liver
