What is osmosis?

Back

The movement of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the role of the matrix in cellular respiration?

Back

The matrix is the site of the Krebs cycle, where acetyl-CoA is oxidized to produce NADH and FADH2.

Front

Where does ATP synthesis occur during photosynthesis?

Back

ATP synthesis occurs in the grana/thylakoid membrane during the light-dependent reactions.

Front

What is the function of membrane-bound organelles in eukaryotic cells?

Back

They compartmentalize intracellular processes, allowing for more efficient cellular function.

Front

What is the role of the cristae in cellular respiration?

Back

Cristae are the inner membrane folds of mitochondria where ATP synthesis occurs during oxidative phosphorylation.

Front

Define hypertonic solution.

Back

A hypertonic solution has a higher solute concentration compared to another solution, causing cells to lose water.

Front

Define hypotonic solution.

Back

A hypotonic solution has a lower solute concentration compared to another solution, causing cells to gain water.

Front

What is the significance of the thylakoid membrane in photosynthesis?

Back

The thylakoid membrane contains chlorophyll and is the site of the light-dependent reactions, where light energy is converted to chemical energy.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both.

Front

What is the function of ATP in cellular processes?

Back

ATP serves as the primary energy currency of the cell, providing energy for various biochemical reactions.
