, Respiration·
respiration the chemical reaction that breaks down nutrient molecules in living cells to release energy
·
Mitochondria is not necessary for respiration to happen
·
energy is always present as an end product
·
uses of the produced energy
·
muscle contractions ·
cell division
growth
·
maintaining body temperature
·
protein synthesis
·
passing nerve impulses
·
aerobic respiration the breakdown of glucose in the presence of oxygen to release a large amount of energy
occurs in every living plant and animal cell

process /in muscles) -
when there is a lack of oxygen delivered to the muscle cells , It will lead to oxygen debt
·
With a high level of lactic acid , It will cause fatigue and muscle ache
·
concentration of CO2 and lactic acid in tissues and blood increases and the blood pH decreases
· the intercostal muscles will be stimulated to contract harder and more often
· the hard and fast contraction leads to faster and deeper breathing
* the heart beats faster to get more O2 in the blood
* the blood cannot supply enough O2 to maintain aerobic respiration as muscle cells use up a lot of energy
