B9 - respiration

Aerobic respiration, exo or endo reaction

Aerobic respiration, exo or endo reaction

Exo because it gives out energy

Aerobic respiration equation

glucose + oxygen → carbon dioxide + water

why is ANAerobic not as effective as AErobic

-The glucose molecules don’t get broken down completely

-Transfers less energy

where does respiration happen

mitochondria

what do animals use respiration for

-contraction of muscles

-regulates temperature

what do plants use respiration for

-energy moves minerals from soil to root hair cells

-converts nutrients into amino acids

What happens in intense excersize

-heart rate increases

-arteries supplying blood widen

-breathing rate increases

-glycogen is converted to glucose to fuel cellular respiration

What is the by-product of anaerobic respiration

lactic acid

What causes muscle fatigue

Build up of lactic acid from anaerobic respiration

How does your body get rid of excess lactic acid

Converted back to glucose in the liver

Why does oxygen debt happen

Oxygen is needed to convert lactic acid into glucose, so you need to keep breathing heavily even after exercise to pay off ur oxygen debt to the Van Der Linde gang…

i guess… im afraid… :(

Oxygen debt repayment

lactic acid+ oxygen → carbon dioxide + water

Metabolism definition

sum of all reactions taking place in cell or body
