ATP and Cellular Respiration

Front

What is ATP and its role in cells?

Back

ATP (adenosine triphosphate) is the primary molecule that distributes energy within cells.

Front

List the properties of ATP that make it ideal for energy distribution.

Back

1. Soluble in water 2. Stable at neutral pH 3. Impassable through phospholipid bilayer 4. Easily removable and reattachable 3rd phosphate 5. Efficient energy release.

Front

What are the life processes powered by ATP?

Back

1. Synthesizing Macromolecules (Anabolism) 2. Active Transport 3. Movement.

Front

How does ATP facilitate the synthesis of macromolecules?

Back

ATP hydrolysis provides the necessary energy for linking monomers to form macromolecules.

Front

What is the role of ATP in active transport?

Back

ATP provides energy to move molecules against a concentration gradient.

Front

What processes depend on ATP for movement?

Back

Vesicle formation, chromosome movement during mitosis, cytokinesis, phagocyte locomotion, and muscle contraction.

Front

What is cell respiration?

Back

Cell respiration is a system that produces ATP by releasing energy from carbon compounds.

Front

What is the primary carbon source for most respiration?

Back

Glucose, obtained from food or photosynthesis.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen, while anaerobic respiration does not.

Front

What are the waste products of aerobic respiration?

Back

Water and carbon dioxide.
