What is the location of the Krebs cycle in cellular respiration?

Back

Matrix

Front

What type of membrane transport requires energy input?

Back

Charged ion moving against concentration gradient

Front

What is the primary function of rough ER compared to smooth ER?

Back

Rough ER compartmentalizes the cell; Smooth ER functions in detoxification and lipid synthesis.

Front

Where does ATP synthesis occur during cellular respiration?

Back

Cristae

Front

How does cell size affect the surface area to volume (SA:V) ratio?

Back

As cells increase in size, the SA:V ratio decreases.

Front

What is the function of the thylakoid membrane in photosynthesis?

Back

Site of light-dependent reactions.

Front

Define osmosis in the context of cellular transport.

Back

The movement of water across a semipermeable membrane from an area of low solute concentration to high solute concentration.

Front

What is the role of ribosomes in a cell?

Back

Synthesize proteins by translating mRNA.

Front

Explain the difference between passive and active transport.

Back

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

Front

What is the significance of the fluid mosaic model of the cell membrane?

Back

It describes the structure of the cell membrane as a mosaic of diverse protein molecules embedded in a fluid bilayer of phospholipids.
