cell respiration Flashcards
what is cellular respiration
the process by which cells break down glucose to release energy
what is the word respiration for cellular respiration
glucose + water –> carbon dioxide, water and energy (ATP)
how is the release of energy controlled?
it is captured and stored in the form of adenosine triphosphate and released as needed by breaking the third bond of phosphate.
where does the energy go from cellular respiration
heat and ATP
what percentage of energy goes towards heat and why is this important
60%
heat in cells is important for keeping the body temperature constant.
ADP to ATP cycle
to create ATP from ADP energy and a third phosphate are required. energy from respiration is stored in the 3rd phosphate bond and when the bond is broken energy is released and it goes back to ADP
ADP can be reused.
ADP
adenosine diphosphate
ATP
adenosine triphosphate
what are the 2 types od cellular respiration
anaerobic and aerobic
what is the process of anaerobic respiration?
it occurs when there isn’t enough oxygen to meet the cells demands.
glycolysis is broken down into 2 molecules of pyruvate producing 2 ATP
what is glyclyosis
a sugar molecule
where does anaerobic respiration occur in the cell
in the cytoplasm
the enzymes required are available in the cytosol
what does anaerobic respiration require
glucose
what is the wastes of anaerobic respiration
lactic acid (toxic and needs to be removed)
causes sore muscles
why do you continue to breath heavily after stopping vigorous exercise
your body has created an oxygen debt so it needs to be repaid by converting lactic acid to glucose.
where does aerobic respiration occur
in the mitochondria
procesess involved in aerobic respiration
glycolysis, citric acid cycle, and electron transport system
requirements of aerobic
oxygen and pyruvic acid (from glucose)
wastes of aerobic
water and carbon dioxide
amount of ATP produced in aerobic
up to 38
2- glycolysis
2- citric acid cycle
34- electron transport system.
