Unit 2 AP Biology Insta-Review (Cell Structure & Function)

Front

What is the function of the Rough Endoplasmic Reticulum (Rough ER)?

Back

The Rough ER is involved in protein synthesis, intracellular transport, and providing mechanical support.

Front

What organelle is produced by the Rough ER and Golgi apparatus after their function?

Back

Transport vesicle.

Front

What lipid is commonly found in cell membranes and helps maintain fluidity?

Back

Cholesterol.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a process that allows substances to cross membranes with the assistance of special proteins, without the use of energy.

Front

What is required for facilitated diffusion to occur?

Back

Membrane proteins are required for facilitated diffusion.

Front

What type of transport moves glucose from the gastrointestinal tract into the blood supply?

Back

Facilitated transport.

Front

What is the role of the Golgi apparatus in a cell?

Back

The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

Define active transport.

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy (ATP).

Front

What is the primary function of the cell membrane?

Back

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

Front

What is the difference between simple diffusion and facilitated diffusion?

Back

Simple diffusion does not require proteins and occurs directly through the membrane, while facilitated diffusion requires membrane proteins to help transport substances.
