Question 1

What organelle is responsible for producing ATP through cellular respiration?

Accepted Answer

The mitochondria produces ATP through cellular respiration, earning its nickname 'the powerhouse of the cell.'

Question 2

What type of transport moves substances across a cell membrane from an area of low concentration to high concentration, requiring energy?

Accepted Answer

Active transport requires ATP energy to move substances against the concentration gradient, from low to high concentration.

Question 3

What process describes the movement of water across a semipermeable membrane from an area of low solute concentration to high solute concentration?

Accepted Answer

Osmosis is the passive movement of water across a semipermeable membrane toward the area of higher solute concentration.

Question 4

Which organelle packages and ships proteins to their final destination inside or outside the cell?

Accepted Answer

The Golgi apparatus modifies, packages, and ships proteins to their final destinations within or outside the cell.

Question 5

What is the term for a solution that causes a red blood cell to shrink due to water moving out of the cell?

Accepted Answer

A hypertonic solution has a higher solute concentration than the cell, causing water to leave the cell and the cell to shrink (crenation).
