Cellular Respiration POGIL Test Questions and Answers
What is represented by the hexagon? -
ANSWER -Glucose (6C)
According to Model 2, where does the change
identified in the previous question occur? -
How many carbon atoms (C) are in one molecule ANSWER -Mitochondrial matrix.
of glucose? - ANSWER -6
Note the number of atoms of carbon in pyruvic
How many carbon atoms (C) are in one molecule acid and explain why three molecules of carbon
of pyruvic acid? - ANSWER -3 dioxide are produced. - ANSWER -Each
pyruvic acid molecule contains 3 carbon atoms
and each carbon dioxide molecule contains only
In the process of glycolysis, what happens to 1. 3 x 1= 3
glucose after it crosses the cell membrane into
the cytoplasm of the cell? - ANSWER -It
splits into 2 pyruvic acids when it crossed. Considering the glycolysis produces 2 pyruvic
acid molecules per glucose molecule, how many
total CO2 molecules will be produced from the
Thinking about the number of carbon atoms in complete breakdown of each glucose molecule?
glucose and in pyruvic acid, explain why there is Show a mathematical equation to support your
one molecule of glucose on the left side of the answer. - ANSWER -6 because each
arrow and two molecules of pyruvic acid on the pyruvic acid has 3 carbons and 2 pyruvic
right side of the arrow. - ANSWER -There molecules are produced. (3 x 2 =6)
is only 3 carbon in pyruvic acid, so since glucose
had 6 carbon, it split into 2 pyruvics making 6
altogether. What 2 hydrogen carrying molecules are formed
during the Kreb's cycle? - ANSWER -
NADH, FADH2
How many ATP molecules are produced during
glycolysis? - ANSWER -2
Glycolysis - ANSWER -ATP-2 NADH-2
FADH2-0
Hydrogen-carrying molecules are also produced
during glycolysis. What is the symbols of these
hydrogen-carrying molecules? - ANSWER - Kreb's cycle (1st pyruvic acid) - ANSWER -
NADPH ATP-1 NADH-4 FADH2-1
Does glycolysis occur inside or outside the Kreb's cycle (2nd pyruvic acid) - ANSWER -
mitochondria? - ANSWER -Outside ATP-1 NADH-4 FADH2- 1
According to Model 2, what happens to pyruvic What cell structure is the site for the electron
acid during the Kreb's cycle? - ANSWER -It transport chain? - ANSWER -Inner
turns into 3 molecules of carbon dioxide. Mitochondrial Membrane
