RESPIRATION Flashcards
what is needed for aerobic respiration? (reactants)
glucose and oxygen
what are the end products of aerobic respiration?
ATP energy and carbon dioxide, water as waste products
what is the definition of aerobic respiration?
the process where cells uses glucose and oxygen to produce energy (ATP), carbon dioxide and water which is needed for life processes in cells
what is the word equation for aerobic respiration?
Glucose + oxygen -> ATP + water + carbon dioxide
what is the symbol equation for aerobic respiration?
C6H12O6 + 6O2 –> ATP + 6H2O + 6CO2
where does aerobic respiration take place?
in the mitochondria
when does anaerobic respiration occur?
when there is little or no oxygen available, for example during intense exercise or in environments where oxygen is limited.
when does aerobic respiration occur?
when there is sufficient oxygen available, such as during normal activities or moderate exercise.
what is the end products of anaerobic respiration?
animals: fermentation in muscles produces a small amount of ATP as well as lactic acids as a bi-product
what are the features which maximise the rate of aerobic respiration in cells?
by having wavy cristae, which increase the surface area for respiration, and by having different numbers of mitochondria depending on energy needs.
why does aerobic respiration make more ATP than anaerobic?
because aerobic uses oxygen to fully break down glucose, resulting more energy, anaerobic only partially breaks down glucose.
when would anaerobic respiration occur in the human body? why?
when oxygen supply is low because the muscles need energy quickly, without enough oxygen they rely on anaerobic respiration to produce ATP.
how is surface area maximised inside the mitochondria, and what effect does this have on aerobic respiration?
more surface area allows more enzymes and proteins involved in the electron transport chain to be present,
more efficient energy production.
