Biology Review III

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes decrease the activation energy of the reaction, allowing it to proceed faster.

Front

How does the Golgi apparatus interact with ribosomes?

Back

The Golgi apparatus sorts and packages proteins created by ribosomes.

Front

What is the function of embedded proteins in the plasma membrane?

Back

Embedded proteins allow certain kinds of molecules to enter or leave a cell.

Front

Which organelle is NOT found in both plant and animal eukaryotic cells?

Front

What happens to a balloon containing a 10% sugar solution when placed in a 5% sugar solution?

Back

The balloon will gain water by osmosis.

Front

Define osmosis.

Back

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

Front

What is the function of mitochondria in eukaryotic cells?

Back

Mitochondria are the powerhouse of the cell, generating ATP through cellular respiration.

Front

What is homeostasis in biological systems?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite external changes.

Front

What is the function of vacuoles in plant cells?

Back

Vacuoles store nutrients, waste products, and help maintain turgor pressure in plant cells.

Front

What is the primary function of ribosomes?

Back

Ribosomes are responsible for protein synthesis in the cell.
