Georgia Milestone Biology Review

Front

What is the function of the Golgi apparatus in a cell?

Back

The Golgi apparatus sorts and packages proteins created by ribosomes, playing a crucial role in maintaining cell homeostasis.

Front

How do enzymes affect metabolic reactions in living organisms?

Back

Enzymes speed up metabolic reactions, allowing organisms to obtain energy quickly.

Front

What type of transport requires cellular energy?

Back

Active transport requires cellular energy to move substances against their concentration gradient.

Front

What happens to water movement in a solution with different sucrose concentrations?

Back

Water will move from a compartment with lower sucrose concentration to a compartment with higher sucrose concentration by osmosis.

Front

How do embedded proteins function in a plasma membrane?

Back

Embedded proteins allow certain kinds of molecules to enter or leave a cell, facilitating selective permeability.

Front

Define homeostasis in the context of cellular function.

Back

Homeostasis is the process by which cells maintain a stable internal environment despite changes in external conditions.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the sites of protein synthesis, where amino acids are assembled into proteins based on mRNA instructions.

Front

Explain the difference between passive and active transport.

Back

Passive transport does not require energy and moves substances down their concentration gradient, while active transport requires energy to move substances against their gradient.

Front

What is osmosis?

Back

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

Front

What is the significance of the plasma membrane in cells?

Back

The plasma membrane regulates what enters and exits the cell, maintaining homeostasis and protecting the cell's internal environment.
