11/19 UNIT TEST Cell Membrane Structure & Function

Front

What type of molecular transport involves the cell engulfing material from the outside environment?

Back

Endocytosis

Front

What is the primary function of mitochondria in a cell?

Back

Mitochondria use oxygen to break down sugar for ATP.

Front

What is the reactant that enters the Calvin Cycle?

Back

CO2

Front

What is the end product of the Calvin Cycle?

Back

Sugar.

Front

What distinguishes rough Endoplasmic Reticulum from smooth Endoplasmic Reticulum?

Back

Rough ER has ribosomes, while smooth ER does not.

Front

What organelle is responsible for capturing sunlight during the light-dependent reactions of photosynthesis?

Back

Chloroplast.

Front

What is the role of the cell membrane in cellular transport?

Back

The cell membrane regulates what enters and exits the cell.

Front

Define passive transport and give an example.

Back

Passive transport is the movement of molecules across the cell membrane without energy input; an example is diffusion.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis.

Front

What is the significance of the fluid mosaic model in understanding cell membranes?

Back

The fluid mosaic model describes the structure of cell membranes as a mosaic of various components that move fluidly.
