What is cellular respiration?

Back

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

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 biological processes.

Front

What is the function of nucleic acids?

Back

Nucleic acids, such as DNA and RNA, store and transmit genetic information.

Front

What is the plasma membrane?

Back

The plasma membrane is a biological membrane that separates and protects the interior of the cell from the external environment.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose and oxygen.

Front

What is passive transport?

Back

Passive transport is the movement of particles across a cell membrane from an area of high concentration to an area of low concentration without the use of energy.

Front

What is active transport?

Back

Active transport is the movement of particles across a cell membrane from an area of low concentration to an area of high concentration, requiring energy.

Front

What is the function of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions in the body by lowering the activation energy required.

Front

What is the significance of the mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, where cellular respiration occurs and ATP is produced.
