Q

Why is oxygen needed later in anaerobic respiration?

A

Oxygen is needed later to break down lactic acid (this is called oxygen debt).

Q

Why is Respiration Important?

A

Energy from respiration is used for:
✔ Movement (muscle contraction)
✔ Keeping warm
✔ Growth and repair
✔ Active transport (moving substances in and out of cells)

Q

why do organisms need energy?

A

Organisms need energy for

Chemical reactions to build larger molecules

movement

keeping warm

17
Q

what’s anaerobic respiration in yeast called?

A

Anaerobic respiration in yeast cells is called fermentation a

18
Q

what’s oxygen debt

A

oxygen debt is the extra oxygen your body needs after exercise to remove lactic acid and restore your body to normal

19
Q

What’s metabolism?

A

metabolism is the sum of all chemical reactions in the body or the cell
