Process of releasing energy from the breakdown of organic
compounds (usually glucose)
Energy is used to fuel metabollic processes - necessary
chemical reactions that take place in the body
Energy is transferred to the environment, so its exothermic
Cellular respiration is an axothermic reaction which releases
energy (ATP) for the necessary metabollic processes and
occurs continuously in every cell of living organisms
Needed for reactions that involve building up larger molecules
from smaller ones Energy from respiration
Needed for muscle contraction
Needed fro active transport
Respiration using oxygen, 30 ATP released
Respiration
Most of the reactions in aerobic respiration happen inside cell
structures called mitochondria
Aerobic respiration
glucose + oxygen --> carbon dioxide + water
Vigorous exercise means that the body can't supply enough
oxygen to your muscles for aerobic respiration
Respiration without oxygen, only 2ATP
Incomplete breakdown of glucose, making lactic acid
Glucose --> lactic acid + (energy)
Doesn't transfer as much energy as aerobic respiration, so is Anaerobic respiration
much less effiient and is only used in emergencies
