Front

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

Back

The Krebs cycle occurs in the matrix of the mitochondria.

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 happens to water movement in a cell with a 1.0M concentration in a 0.5M exterior solution?

Back

The cell with 1.0M concentration will gain water from the 0.5M exterior solution.

Front

Where do the light-dependent reactions of photosynthesis take place?

Back

The light-dependent reactions occur in the grana/thylakoid membrane.

Front

What is the function of vacuoles in plant cells?

Back

Vacuoles are responsible for storage and release of macromolecules and cellular waste products, and they aid in turgor.

Front

Define cellular respiration.

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the role of the mitochondria in a cell?

Back

Mitochondria are known as the powerhouse of the cell, where ATP is produced through cellular respiration.

Front

Explain the significance of the SA:V ratio in cells.

Back

A higher SA:V ratio allows for more efficient exchange of materials between the cell and its environment.

Front

What is osmosis?

Back

Osmosis is 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 function of chloroplasts in plant cells?

Back

Chloroplasts are responsible for photosynthesis, converting light energy into chemical energy in the form of glucose.
