ATP is made out of

3 phosphate, sugar ribose. and nitrogen containing adenine

The process by which substances are moved into a cell by vesicle formation is called

endocytosis

In a coupled reaction, ______ released from an energy-releasing reaction is used to drive an ______ reaction.

energy; energy-requiring

These are three of the following are advantages of using ATP as an energy carrier in living systems.

1. ATP breakdown releases a sufficient amount of energy for a biological purpose. 2. ATP releases energy quickly, which facilitates the speed of enzymatic reactions. 3. The structure of ATP allows it to be coupled to an energy-requiring reaction

During the ATP cycle, ATP loses ______ when it is broken down into ADP + P and ______ is/are stored when ADP + P is converted back to ATP.

Energy, energy

When ATP is used as an energy source, a phosphate group is removed by hydrolysis. How is ATP regenerated during the ATP cycle?

In the mitochondria through cellular respiration

Identify the major outputs from the light reaction.

NADPH ATP O2

ATP is coupled to an energy-requiring reaction when ATP is used to energize, or change the _______ , of a reactant.

SHAPE

Select all the of the correct differences between receptor-mediated endocytosis and pinocytosis.

Unlike pinocytosis, receptor-mediated endocytosis allows cells to take in a specific molecule. Unlike pinocytosis, receptor-mediated endocytosis requires a specific receptor protein to recognize a specific molecule.

Molecules that undergo exocytosis from a cell are enclosed in ______.

Vesicles

The activity of most enzymes and metabolic pathways is regulated by _________.

feedback inhibition.

for ATP to be stable (ADP}

it needs 2 phosphates rather than 3

The process by which a cell takes in larger particles by means of vesicle formation is called ______.

phagocytosis
