Fall ACP Review 24.25 (part 1 of 3)

Front

What is endocytosis?

Back

Endocytosis is a type of cell transport where the cell engulfs material from the outside environment, bringing it into the cell.

Front

What is exocytosis?

Back

Exocytosis is the process by which a cell expels materials to the outside environment, often using vesicles.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, typically along the concentration gradient.

Front

What happens at the G1 checkpoint?

Back

At the G1 checkpoint, the cell checks for DNA damage and ensures that the cell is ready for DNA synthesis.

Front

What happens at the G2 checkpoint?

Back

At the G2 checkpoint, the cell checks to ensure that DNA has been replicated correctly and that the cell is ready to enter mitosis.

Front

What is the M (spindle) checkpoint?

Back

The M checkpoint ensures that all chromosomes are properly attached to the spindle apparatus before the cell proceeds with mitosis.

Front

How do cancer cells relate to the cell cycle?

Back

Cancerous cells arise when the checkpoints of the cell cycle fail, leading to uncontrolled cell division.

Front

What is the optimum pH for enzyme activity?

Back

The optimum pH is the pH at which an enzyme's activity is at its maximum.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing the cell to swell as water enters.
