Cellular Processes Test Review

Front

What is Homeostasis?

Back

Homeostasis is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation.

Front

What phase of cell division is characterized by the condensation of chromatin into chromosomes?

Back

Prophase

Front

What are the reactants of photosynthesis?

Back

The reactants of photosynthesis are H₂O + CO₂ + Sunlight.

Front

How are photosynthesis and respiration related?

Back

The products of one are the reactants of the other.

Front

What is Endocytosis?

Back

Endocytosis is a type of active transport where cells engulf substances from the outside environment.

Front

What is Exocytosis?

Back

Exocytosis is a process where cells expel materials to the outside environment.

Front

Define Cellular Respiration.

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the role of ATP in cellular processes?

Back

ATP (adenosine triphosphate) serves as the primary energy carrier in cells.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.

Front

What is the function of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that absorbs light energy, primarily from the sun, to drive the process of photosynthesis.
