All the chemical reactions that take place inside a cell are collectively referred to as?

Metabolism

Exactly where in the mitochondria does the Citric Acid Cycle take place?

Mitochondrial Matrix

Where are the proteins of the electron transport chain located?

Mitochondrial inner membrane

During glycolysis, how many ATP molecules (net) are produced by each molecule of glucose?

2

One molecule of 6-carbon glucose, allows the Citric Acid Cycle to turn how many times?

2 times

Each turn of the Citric Acid Cycle produces...

3NAGH, 1FADH2, 2 carbon dioxide, 1ATP

The primary energy currency/molecule of the cell is...

ATP

Which enzyme is responsible for ATP generation by the process of chemiosmosis?

ATP synthase

In the mitochondria, 3-carbon pyruvate/pyruvic acid is initially transformed into which two-carbon molecule?

Acetyl CoA

After pyruvate/pyruvic acid production, carbon dioxide is released. During which stages does this carbon dioxide release occur?

Both conversion of pyruvate acid to acetyl CoA and the Citric Acid Cycle.

In order to obtain energy our bodies must harvest energy from carbohydrates such as glucose molecules. The equation for this chemical reaction is?

C6H12O6+O2 -> H2O+CO2 (Glucose+Oxygen -> Water+Carbon Dioxide)

Which term most precisely describes the cellular process of breaking down large molecules into smaller ones?

Catabolism

Where does glycolysis take place in eukaryotic cells?

Cytoplasm

D) None of these answers are correct, as all are examples of energy transformation

Oxidative phosphorylation has two stages, what are they?

Electron Transport Chain & Chemiosmosis

You and your best friend just rode your bike up a large hill, you say to your friend, "I am tired and out of energy." Your friend, who is a physics major says which true statement:

Our bikes were using kinetic energy to get up the hill, but now they have potential energy.

Which of the following stages of glucose catabolism (breakdown) produces the most ATP?

Oxidative phosphorylation (electron transport chain + chemiosmosis)

Which molecule is the terminal electron acceptor in the electron transport chain?

Oxygen

Which 3-carbon molecules is produced by the end of the glycolysis?

Pyruvate

Judy, a biologist, was told by a colleague that the power company created electricity to be used in the science buildings. Judy told him that was impossible because...

energy cannot be created or destroyed but only converted from one from to another.
