Lab 5 Flashcards
what is photosynthesis
the process of transferring the suns energy to organic molecules
what is cellular respiration
cellular process that releases the energy pf glucose to synthesize ATP
what is fermentation
process that some organisms use to produce energy
is fermentation anaerobic or aerobic
anaerobic
if cellular respiration anaerobic or aerobic
aerobic
what is anaerobic
absence of oxygen
what is aerobic
utilizing oxygen
what type of reactions are involved in cellular respiration and fermentation
oxidation-reduction reactions (redox)
what happens during oxidation
loss of electrons
what happens during reduction
gain of electrons
how does a redox reaction work in cellular respiration
two hydrogen atoms are removed from glucose
how does cellular respiration work
two hydrogen atoms are removed from glucose and transferred to a coenzyme called NAD+, reducing this compound to NADH
what is NAD+
nicotinamide adenine dinucleotide
where does NADH transfer electrons to
electron transport chain
when the transfer of electrons happens from molecule to another, what is released
energy that can be used to synthesize ATP
what are the three stages of cellular respiration
- glycolysis
- citric acid cycle
- electron transport chain
where does gylcolysis occur
in the cytoplasm
where does the citric acid cycle take place
mitochondria
where does the electron transport chain occur
mitochondria
what does metabolic stages does fermentation have
glycolysis
what metabolic stages are inhibited when oxygen is low
citric acid cycle and electron transport chain
is fermentation or cellular respiration better at producing ATP
cellular respiration
what is the max amount of ATP cellular respiration can produce
32 ATP molecules
what is the max amount of ATP fermentation can produce
2 ATP molecules
metabolic rate
amount of energy used in a certain time period
how can metabolic rate be measured
monitoring the oxygen usage or the production of CO2
what metabolic rate is being tested in the lab
Lumbricina
