Removes a CO2 from pyruvate
During cellular respiration, acetyl-CoA is formed during a reaction that also does what?
glucose
During glycolysis, one molecule of "blank" is broken down into two molecules of pyruvate, driving the synthesis of ATP
NAD+ to NADH
During the breakdown of pyruvate, two high-energy electrons are removed from it. These are then used to convert
Fructose-1,6-bisphosphate
During the energy investment phase of glycolysis, glucose is converted to which molecule?
two molecules of pyruvate
Glycolysis involves the breakdown of one molecule of glucose into
cytosol
Glycolysis occurs in the
all but glycolysis
In eukaryotic cells, which of the following metabolic pathways occur in the mitochondria?
Substrate
The ATP produced during glycolysis is the result of "blank" -level phosphorylation.
increasing the surface area of the inner mitochondrial membrane
The cristae increase the amount of ATP that can be made by
plasma, inner
The location of oxidative phosphorylation in prokaryotes is the "blank" membrane and in eukaryotes is the "blank" mitochondrial membrane

The number of ATP molecules hydrolyzed during the first stage of glycolysis is
cellular respiration
The principal energy-yielding pathway that involves the breakdown of glucose in the presence of oxygen is called
prime glucose for the exergonic reactions to follow
The purpose of the energy investment phase of glycolysis is to

The pyruvate molecule produced in glycolysis undergoes a reaction which results in the production of one "blank" group and one CO2 molecule.
ATP, NADH, FADH2
The three energy intermediates produced during cellular respiration are
Chemiosmosis
The use of energy stored in a proton gradient to drive the synthesis of ATP is called
One acetyl group One NADH molecule One CO2
What are the products of the breakdown of a single pyruvate molecule?
glycolysis, breakdown of pyruvate, citric acid cycle, oxidative phosphorylation,
What four pathways are involved in the breakdown of glucose to carbon dioxide and water?
It enters the citric acid cycle.
What happens to the acetyl-CoA that is produced from pyruvate?
NADH
What is produced during the oxidation of glyceraldehyde-3-phosphate?
Production of ATP
What is the main function of oxidative phosphorylation? Multiple choice question.
ATP
What is the main product of cellular respiration?
NAD+
When pyruvate is broken down, the acetyl group is attached to coenzyme A, and two high-energy electrons are transferred to
Increase surface area Allow for greater ATP production Are called cristae
Which of the following statements about invaginations of the inner mitochondrial membrane are true?
To raise its free energy so that later reactions can be exergonic
Why are phosphate groups added to glucose during the first phase of glycolysis?
false
the process of glycolysis takes place in the mitochondria.
