Photosynthesis - WHS

What are the three parts of an ATP molecule?

• deoxyribose sugar, phosphate groups, and a nitrogen base

• ribose sugar, phosphate groups, and a nitrogen base

• amino acid, ribose sugar, and phosphate groups

• monosaccharide, amino acid, and phosphate groups

What high-energy molecule is created during cellular respiration for use in powering cell processes?

• ATP

• CO2

• glucose

• water

In which organelle do the light-independent reactions of photosynthesis occur?

• Mitochondria

• Stroma

• Thylakoid Membrane

• Granule

In which organelle do the chemical reactions of photosynthesis occur?

• Rough Endoplasmic Reticulum

• Thylakoid Membrane

• Stroma

• Chloroplast

During which stage of photosynthesis is oxygen produced?

• Calvin cycle

• electron chain

• light dependent

• light independent

How does the Calvin cycle (light-independent reactions) differ from the light-dependent reactions of photosynthesis?

• The Calvin cycle requires light energy.

• The Calvin cycle takes place in the stroma.

• The Calvin cycle takes place in the thylakoid membrane

• The Calvin cycle is the first stage of photosynthesis.

Which step is a part of the dark (light-independent) reactions?

• ATP molecules are produced.

• Solar energy is absorbed by chloroplasts.

• Oxygen is released when water molecules are split.

• Carbon dioxide is used to form simple sugars.

What are the products of photosynthesis?

• lipids and a molecule essential for lactic acid fermentation

• carbohydrates and a molecule essential for aerobic cellular respiration

• starches and a molecule essential for alcoholic fermentation

• sugars and a molecule essential for anaerobic cellular respiration

Which statement best describes the light-dependent reactions of photosynthesis?

• They require solar energy and produce energy-storing molecules.

• They require solar energy and produce oxygen as the main product.

• They require solar energy and produce simple sugars from carbon dioxide.

• They require solar energy and produce carbon dioxide as the main product.

The light-dependent reactions of photosynthesis capture solar energy that is used to create energy-storing molecules and to split water. What is a waste product of the light-dependent reactions?

• ATP

• CO2

• NADPH

• O2
