Front

Why are cells typically small in size?

Back

Cells are small to maximize their surface area-to-volume ratio, which is essential for efficient nutrient uptake and waste removal.

Front

Which of the following is most likely an enzyme?

Back

Amylase is an enzyme that helps in the digestion of carbohydrates.

Front

What is the role of enzymes in biological reactions?

Back

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

Front

Define the term '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 function of the mitochondria?

Back

Mitochondria are the powerhouse of the cell, where cellular respiration and energy production occur.

Front

Explain the significance of the surface area-to-volume ratio in cells.

Back

A higher surface area-to-volume ratio allows for more efficient exchange of materials between the cell and its environment.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and organelles.
