Glycolysis and Cellular Respiration: Breathing for Cells? Not So Much Quiz

Think you’ve got your head wrapped around Glycolysis and Cellular Respiration? Put your knowledge to the test. Good luck — the Stickman is counting on you!
Q. Cellular respiration refers to

the transferring of oxygen to each cell in the body
the breaking down of sugars without oxygen present
the splitting of glucose molecules into pyruvate
the using of oxygen as a reactant to break down food into bioavailable energy
the manufacturing of ATP using ATP synthase
Q. In the electron transport chain, oxygen

becomes a reducing agent
is the first electron acceptor
is the last electron acceptor
drives the production of ATP
is unnecessary
Q. Scientists believe that mitochondria and chloroplasts arose through endosymbiosis. What evidence is true and supports this claim?

Both organelles have their own DNA.
Mitochondria evolved relatively recently compared to chloroplasts.
Fossil records exist of free-living mitochondria.
Chloroplasts are where photosynthesis occurs.
Mitochondria host the electron transport chain.
Q. The energy used in making ATP from ADP in chemiosmosis is from

the conversion of glucose to pyruvate
the stream of protons crossing the inner mitochondrial membrane
potassium pumps
the citric acid cycle
Q. During the transition step before the citric acid cycle, what conversion happens?

Oxygen to water
Pyruvate to glucose
Glucose to pyruvate
Pyruvate to acetyl-CoA
Acetyl-CoA to pyruvate
Q. Which of the following is NOT a product of energy metabolism?

Carbon dioxide
Lactic acid
Q. The citric acid cycle is called a "cycle" because

what goes around, comes around
it was discovered by Mr. Tri Cycle
the acetyl-CoA from the beginning is regenerated at the end
the oxaloacetate from the beginning is regenerated at the end
it makes a circular shape in the mitochondria
Q. When FADH2 enters the electron transport chain, what happens?

It makes more ATP than when NADH donates electrons.
It makes less ATP than when NADH donates electrons.
ATP production stops completely.
The electron transport chain runs in reverse.
Ethanol is made as a byproduct.
Q. During the redox reactions of the electron transport chain, where do protons move?

Across the inner mitochondrial membrane
Across the outer mitochondrial membrane
Into the mitochondrial matrix
Out of the intermembrane space
Into the cytoplasm
Q. Which of the following likely evolved first?

Oxidative phosphorylation
The electron transport chain
