Glycolysis results in a net profit of _____ ATP's.

2

For each acetyl-coenzyme A (acetyl-CoA) which enters the citric acid cycle, _____ will be produced.

3 NADH, 1 FADH2, and 1 ATP.

In aerobic cellular respiration, each molecule of glucose results in _____ ATP molecules.

36-38

The electron transport chain and chemiosmosis produce _____ ATP from each NADH and _____ ATP from each FADH2 entering the system.

3; 2

The membrane protein, _____, will catalyze the reaction ADP + P ATP as H+'s diffuse through this protein from the intermembrane space into the matrix.

ATP synthase

An enzyme is a catalyst which allows chemical reactions to slow down by lowering the activation energy of the reactions. Group starts. True or False

False

The light-dependent reactions of photosynthesis occur in the stroma of the chloroplast. true or false

False

Protons (H+) accumulate in the thylakoid space during electron transport on the thylakoid membrane. Which of the following describes what will happen to these protons next?

The protons will diffuse from the thylakoid space to the stroma through ATP synthase that generates ATP.

Why are plants green?

They reflect green wavelengths of light and absorb other colors of the visible light spectrum.

The breakdown of glucose in aerobic cellular respiration is a type of catabolism. True or False

True

The final electron acceptor in aerobic cellular respiration is oxygen which accepts electrons thus becoming reduced. True or False

True

The dark reactions use _____ to form organic molecules such as sugars.

carbon dioxide

The main pigment used in photosynthesis is

chlorophyll.

Chemical reactions that release energy are called _____ reactions.

exergonic

Which process produces ethanol or lactic acid (lactate)?

fermentation

The metabolic pathway below involves how many possible chemical reactions? A->B->C->D->E

four

Which of these processes occurs in the cytoplasm?

glycolysis

The first phase of aerobic cellular respiration is

glycolysis.

For this question, please note that the conversion of pyruvate to acetyl-coenzyme A (acetyl-CoA) is also called the preparatory (prep) reaction. The correct sequence for aerobic metabolic breakdown (aerobic cellular respiration) of glucose is

glycolysis—preparatory reaction—citric acid cycle—electron transport system.

The sum of all of the chemical reactions in an organism and it's cells constitute

metabolism.

While we are sitting down to lunch, we are consuming _____ energy, which will then be converted into _____ energy as we work until dinner time.

potential; kinetic

Most enzymes are made up of _____, but some are made up of _____.

protein; RNA

Granum refers to

stack of thylakoids

Which process produces both NADH and FADH2?

the citric acid cycle

The metabolic process that produces the most ATP is

the election transport chain (system) with ATP synthase.
