The Powerhouse Duo: Cellular Respiration and Photosynthesis

What is the main purpose of cellular respiration?

• To break down food molecules to release energy

• To produce food for the cell

• To create oxygen for the cell to use

• To help the cell grow in size

In which part of the cell does photosynthesis occur?

• Mitochondria

• Ribosomes

• Chloroplasts

• Nucleus

What are the reactants of photosynthesis?

• Glucose and oxygen

• Carbon dioxide and water

• Sunlight and chlorophyll

• ATP and NADPH

Which of the following is NOT a product of cellular respiration?

• Carbon dioxide

• Water

• Glucose

• ATP

What is the role of chlorophyll in photosynthesis?

• It helps in the digestion of food

• It captures light energy from the sun

• It breaks down sugar molecules

• It transports water to the leaves

Which process occurs in the mitochondria of a cell?

• Photosynthesis

• Cellular respiration

• Protein synthesis

• DNA replication

What is the main energy currency of the cell?

• Glucose

• Carbon dioxide

• ATP

• Oxygen

What gas is taken in by plants during photosynthesis?

• Oxygen

• Nitrogen

• Carbon dioxide

• Hydrogen

Which of the following is a product of photosynthesis?

• Carbon dioxide

• Oxygen

• ATP

• Glucose

Which of these statements is true about lipids and the cell wall?

• Lipids help the cell wall stay strong.

• Lipids are only found inside the cell, while the cell wall is made of sugars.

• Lipids help the cell breathe, while the cell wall protects the cell.

• Lipids make the cell membrane flexible and strong, but the cell wall is made of sugars and proteins.
