Cell Processes Review AI

Front

What is endocytosis?

Back

Endocytosis is the process by which cells take in large molecules by engulfing them with their cell membrane, forming a vesicle.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert sunlight, water, and carbon dioxide into glucose (energy) and oxygen.

Front

What is passive transport?

Back

Passive transport is the movement of molecules across a cell membrane without the use of energy, typically moving from an area of higher concentration to an area of lower concentration.

Front

What is active transport?

Back

Active transport is the process of moving molecules across a cell membrane against their concentration gradient, requiring energy (ATP) to do so.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is 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 a concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance across a space, which drives the movement of molecules from high to low concentration.

Front

What role do chloroplasts play in photosynthesis?

Back

Chloroplasts are organelles in plant cells that contain chlorophyll and are responsible for capturing sunlight to convert it into chemical energy during photosynthesis.

Front

What is the function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and structural support.

Front

What is the significance of glucose in cellular processes?

Back

Glucose is a primary energy source for cells, used in cellular respiration to produce ATP, which powers various cellular activities.
