Cell Processes!

Front

What is Exocytosis?

Back

Exocytosis is the process by which cells move large particles out of the cell by vesicles fusing with the plasma membrane.

Front

What is the main component of the plasma membrane?

Back

The main component of the plasma membrane is lipids, specifically phospholipids.

Front

What is Facilitated Diffusion?

Back

Facilitated Diffusion is a type of passive transport that allows substances to cross membranes with the assistance of special proteins.

Front

What is Active Transport?

Back

Active Transport is the movement of molecules across a membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is Osmosis?

Back

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

Front

What is Endocytosis?

Back

Endocytosis is the process by which cells take in large particles by engulfing them in a vesicle.

Front

What is the difference between Active Transport and Passive Transport?

Back

Active Transport requires energy to move substances against their concentration gradient, while Passive Transport does not require energy and moves substances along their concentration gradient.

Front

What role do proteins play in the plasma membrane?

Back

Proteins in the plasma membrane help with transport, act as receptors, and provide structural support.

Front

What is the function of Protein Pumps?

Back

Protein Pumps are integral membrane proteins that actively transport ions or molecules across the membrane against their concentration gradient.

Front

What is Cytoplasmic Streaming?

Back

Cytoplasmic Streaming is the movement of the fluid substance (cytoplasm) within a cell, which helps distribute nutrients and organelles.
