Keystone Biology Module 1 Part 1

Front

What process occurs in mitochondria?

Back

Energy is released from glucose molecules.

Front

How does the structure of the plasma membrane serve the needs of the cell?

Back

It is embedded with proteins, which permit the passage of certain materials.

Front

What does it mean for a plasma membrane to be 'selectively permeable'?

Back

It only allows certain substances to pass into or out of a cell.

Front

How does a cell reuse ADP after energy is released from ATP?

Back

It is recombined with phosphates for reuse.

Front

What is the simplest level of biological organization that can support life functions?

Back

cell.

Front

What is the function of mitochondria in a cell?

Back

Mitochondria are responsible for energy production through the process of cellular respiration.

Front

What is the role of proteins in the plasma membrane?

Back

Proteins in the plasma membrane facilitate the transport of materials in and out of the cell.

Front

What is the difference between passive and active transport?

Back

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

Front

What is the structure of a phospholipid?

Back

A phospholipid consists of a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.
