BMST Cellular Processes and Organelles 3

Question 1

Which organelle packages and ships proteins to their final destinations?

Accepted Answer

Golgi apparatus

Answer

The Golgi apparatus modifies, packages, and directs proteins to their correct locations inside or outside the cell.

Question 2

What is osmosis?

Accepted Answer

Movement of water across a semipermeable membrane from low to high solute concentration

Answer

Osmosis is the passive diffusion of water molecules across a semipermeable membrane toward areas of higher solute concentration.

Question 3

Which cellular process requires oxygen as a final electron acceptor?

Accepted Answer

Aerobic respiration

Answer

Aerobic respiration uses oxygen in the electron transport chain to produce large amounts of ATP.

Question 4

What is the function of centrioles in animal cells?

Accepted Answer

Organizing the mitotic spindle during cell division

Answer

Centrioles form the spindle fibers that pull chromosomes to opposite poles during cell division.

Question 5

Which process moves substances against their concentration gradient and requires energy?

Accepted Answer

Active transport

Answer

Active transport uses ATP to move molecules from low to high concentration, against their natural gradient.
