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
