|
does glycolysis release a great amount of energy?
|
false
|
|
|
what would be the problem if cellular respiration took place in just one step?
|
most of the energy would be lost in the form of light and heat which the cell can't control
|
|
|
what is the function of NAD+ in glycolysis?
|
holds the high-energy electrons removed from glycolysis until they can be transferred to other molecules
|
|
|
NAD+ helps to pass _____ from _____ to other pathways in the cell
|
energy, glucose
|
|
|
why can glycolysis supply energy to cells when oxygen is not available?
|
it's anaerobic / it doesn't require oxygen
|
|
|
what problem does a cell have when it generates large amounts of ATP from glycolysis?
|
all the available NAD+ molecules are filled up with electrons and without NAD+, the cell can't keep glycolysis going, and ATP production stops
|
|
|
how does fermentation allow glycolysis to continue?
|
it converts NADH to NAD+ by passing electrons back to pyruvic acid
|
|
|
because fermentation doesn't require oxygen, it's said to be _____
|
anaerobic
|
|
|
what organisms use alcoholic fermentation?
|
yeasts and few other microorganisms
|
|
|
what happens to the small amount of alcohol produced in alcoholic fermentation during the baking of bread?
|
it evaporates
|
|
|
what does lactic acid fermentation convert into lactic acid?
|
glucose
|
|
|
what is the equation for lactic acid fermentation after glycolysis?
|
pyruvic acid + NADH --> lactic acid + NAD+
|
|
|
during rapid exercise, how do your muscle cells produce ATP?
|
by lactic fermentation
|
