False
During the electron transport chain, energy from the molecules _____ is used to pump hydrogen ions into the _____.
NADH and FADH2 ... mitochondrial matrix
NADH and FADH2 ... intermembrane space
NADH ... intermembrane space
NADH ... mitochondrial matrix
In dephosphorylation, ATP is hydrolyzed into ADP and inorganic phosphate and _____.
energy remains constant
energy is released
energy is required
Without this molecule, cellular respiration does not happen, because it is the final electron acceptor. What is it?
O2
water
FADH2
CO2
Yeasts are single-celled eukaryotes that don't have a mitochondrion. Can they exist in an environment without oxygen?
Yes, yeasts can exist in an oxygen-poor environment. They will only be able to produce 2 net ATP via fermentation, but the absence of oxygen will not kill the organisms.
No, the presence of oxygen will kill yeast because they will not be able to undergo fermentation.
Sugar is "quick energy" because provides energy to the cell directly, whereas carbohydrates like starch must be broken down before the body can utilize the energy.
