Respiration

Question 1

Uses of energy in the body

Answer 1

Contraction of muscles
passage of nerve impulses
growth
cell divison
active transport
maintenance of constant body tempereture

Question 2

Define aerobic respiration

Answer 2

aerobic respiration are the chemical reactions in cells that use oxygen to break down nutriet molecules to release energy

Question 3

Word equation for aerobic respiration
Balanced

Answer 3

C 6 H 12 O 6 + 6 O 2 → 6 CO 2 + 6 H 2 O
(glucose + oxygen -> carbon dioxide + water).

Question 4

define Unaerobic respiration and state energy release

Answer 4

Unaerobic respiration are the reactions in cells which break down nutrient molecules to release energy without using oxgen
Unaerobic respiration release less energy per glucose molecule as compared to aerobic

Question 5

anaerobic respiration in yeast
balanced

Answer 5

glucose> alcohol+ water
C6H12O6 ⟶ 2C2H5OH + 2CO2

Question 6

equation for vigorous exercise in muscles

Answer 6

glucose>lactic acid

Question 7

define oxygen debt and how it is removed

Answer 7

an oxygen debt happends during vigorous exercise when lactic acids builds up in muscles
There is continuation of fast and deeper breathing to supply oxygen to the liver for aerobic respiration of yeast and to remove carbon di oxide and fast heart rate to trasnport lactic acid in the blood of muscles to the liver
