What is the Cell Theory?

Back

The Cell Theory states that all living organisms are composed of cells, cells are the basic unit of life, and all cells arise from pre-existing cells.

Front

What is ATP?

Back

Adenosine Triphosphate (ATP) is a molecule that carries energy within cells, used for various cellular processes.

Front

What is the difference between endothermic and exothermic reactions?

Back

Endothermic reactions absorb energy from their surroundings, while exothermic reactions release energy.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed in the process.

Front

What is the ATP/ADP cycle?

Back

The ATP/ADP cycle is the process by which ATP is converted to ADP and a phosphate group, releasing energy, and then ADP is converted back to ATP by adding a phosphate group, storing energy.

Front

What are amino acids?

Back

Amino acids are organic compounds that serve as the building blocks of proteins.

Front

What is the function of mitochondria in cells?

Back

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

Front

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 significance of the phosphate group in ATP?

Back

The phosphate group in ATP is crucial for energy storage and transfer; its removal releases energy for cellular work.

Front

What are the main components of a plant cell?

Back

Plant cells have a cell wall, chloroplasts, and a large central vacuole, which are not found in animal cells.
