Respiration

Question 1

uses of energy in living organisms

Answer 1

• muscle contractions
• protein synthesis
• cell division
• active transport
• growth
• passage of nerve impulses
• maintenance of body temp

Question 2

what is the effect on temperature on respiration in yeast

Answer 2

the higher the temperature, the more CO2 will be released by the yeast, forming s greater amount of bubbles

Question 3

what is aerobic respiration

Answer 3

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

Question 4

aerobic respiration word equation

Answer 4

glucose + oxygen –> carbon dioxide + water + energy

Question 5

aerobic respiration chemical equation

Answer 5

C6 + H12 + O6 –> 6CO2 + 6H20 + 36ATP

Question 6

what is anaerobic respiration

Answer 6

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

Question 7

anaerobic respiration releases

Answer 7

much less energy per glucose molecule than aerobic respiration (aerobic respiration releases 18x more than ana)

Question 8

for every 1 glucose molecule, anaerobic respiration releases

Answer 8

2 ATP’s

Question 9

for every 1 glucose molecule, aerobic respiration releases

Answer 9

36 ATP’s

Question 10

word equation for anaerobic respiration in muscles during vigorous exercise

Answer 10

glucose –> lactic acid + energy

Question 11

chemical equation for anaerobic respiration

Answer 11

C6 + H12 + O6 –> C3 + H6 + O3 + 2ATP

Question 12

what causes an oxygen debt

Answer 12

when lactic acid builds up in blood during vigorous exercise, it causes an oxygen debt

Question 13

why is the oxygen debt removed after exercise

Answer 13

• because your heart continues to beat faster, to transport the lactic acid in the blood to the liver
• because you continue to breathe faster and deeper, to supply oxygen for aerobic respiration
• because of aerobic respiration in the liver
