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

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.
