Cellular Processes Test Review

Front

What is homeostasis?

Back

Homeostasis is the process by which cells and organisms maintain a stable internal environment despite changes in external conditions.

Front

How do buffers function in biological systems?

Back

Buffers help maintain pH levels by neutralizing acids and bases, thus stabilizing the internal environment of cells.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy (ATP) to move substances against their concentration gradient, while passive transport does not require energy and moves substances along their concentration gradient.

Front

What are the products of cellular respiration?

Back

The products of cellular respiration are carbon dioxide (CO2), water (H2O), and ATP (energy).

Front

What are the reactants of cellular respiration?

Back

The reactants of cellular respiration are glucose and oxygen (O2).

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

Where does cellular respiration occur in eukaryotic cells?

Back

Cellular respiration occurs in the mitochondria of eukaryotic cells.

Front

What is the role of ATP in cellular processes?

Back

ATP (adenosine triphosphate) serves as the primary energy currency of the cell, providing energy for various cellular activities.

Front

What is diffusion?

Back

Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules across a selectively permeable membrane.
