What is an isotonic solution?

Back

An isotonic solution is a solution where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

Front

Which transport across the membrane requires energy?

Back

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

Front

What process releases chemical energy from sugars to make ATP when oxygen is present?

Back

Cellular respiration is the process that releases chemical energy from sugars and other carbon-based molecules to make ATP when oxygen is present.

Front

What is the waste gas given off by cellular respiration?

Back

The waste gas given off by cellular respiration is carbon dioxide.

Front

What is exocytosis?

Back

Exocytosis is the process by which a cell expels materials in vesicles that fuse with the plasma membrane.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.

Front

What is the role of ATP in cellular processes?

Back

ATP (adenosine triphosphate) serves as the primary energy carrier in cells, providing energy for various cellular functions.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is 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 the function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and support.
