glycolysis
Glycolysis provides a cell with a net gain of
2 ATP molecules
The starting molecule for glycolysis is
glucose
Glycolysis requires
an energy input
Which of the following is NOT a product of glycolysis?
Glucose
Which of the following acts as an electron carrier in cellular respiration?
NAD+
Lactic Acid fermentation occurs in
muscle cells
The two main types of fermentation are called
alcoholic and lactic acid
One cause of muscle soreness is
lactic acid fermentation
Which process is used to produce beer and wine?
alcoholic fermentation
Milk is converted to yogurt under certain conditions when the microorganisms in the milk produce acid. Which of these processes would you expect to be key in production of yogurt?
lactic acid fermentation
During lactic acid fermentation, ____
NAD+ is regenerated, allowing glycolysis to continue
The conversion of pyruvic acid into lactic acid requires
NADH
In the presence of oxygen, glycolysis is followed by
the Krebs cycle
Cellular respiration is called an aerobic process because it requires
Oxygen
Which organism is NOT likely to carry out cellular respiration?
anaerobic bacterium
The starting molecules for the Krebs cycle is
Pyruvic acid
The Krebs cycle does not occur if
fermentation occurs
The Krebs cycle produces
electron carriers
The Krebs cycle starts with
pyruvic acid and yields carbon dioxide
The electron transport chain can be found in
all of the above
Prokaryotes, Animals, Plants
In eukaryotes, electron transport occurs in the
mitochondria
Which of the following passes high-energy electrons into the electron transport chain?
NADH and FADH2
Each pair of high-energy electrons that moves down the electron transport chain provides enough energy to
convert 3 ADP molecules into 3 ATP molecules
The energy of electrons passing along the electron transport chain is used to make
ATP
Breathing heavily after running a race is your body’s way of
repaying an oxygen debt
When the body needs to exercise for longer than 90 seconds, it generates ATP by carrying out
cellular respiration
If you want to control your weight, how long should you exercise aerobically each time that you exercise?
more than 20 minutes
