Photosynthesis

What do plants need for photosynthesis?

• Oxygen

• Glucose

• Carbon dioxide

• Nitrogen

What is the enzyme that fixes carbon from the atmosphere to convert it to glucose?

• RuBisCo (Ribulose Bisphosphate Carboxylase)

• PEP Carboxylase

• Carbonic Anhydrase

• Acetyl-CoA Carboxylase

What is produced during the light-dependent reactions?

• ATP and NADPH

• Glucose and Oxygen

• Carbon Dioxide and Water

• FADH2 and Citric Acid

What is the role of ATP in photosynthesis?

• ATP provides energy for the light-independent reactions (Calvin cycle).

• ATP is used to absorb sunlight during photosynthesis.

• ATP is a byproduct of the light-dependent reactions.

• ATP helps in the formation of glucose from carbon dioxide.

What is the primary pigment involved in photosynthesis?

• Chlorophyll

• Carotene

• Xanthophyll

• Anthocyanin

Which organelle is responsible for photosynthesis?

• Mitochondria

• Chloroplast

• Nucleus

• Ribosome

Where do light-dependent reactions take place in a plant cell?

• Thylakoid membrane

• Cytoplasm

• Mitochondria

• Nucleus

What is the significance of the Calvin cycle?

• It converts carbon dioxide into glucose using ATP and NADPH.

• It is a process that occurs in the mitochondria to produce energy.

• It helps in the synthesis of proteins from amino acids.

• It is responsible for the breakdown of glucose during cellular respiration.

What gas is released as a byproduct of photosynthesis?

• Carbon Dioxide

• Oxygen

• Nitrogen

• Hydrogen

What is the overall chemical reaction for photosynthesis?

• 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

• 6O₂ + C₆H₁₂O₆ → 6CO₂ + 6H₂O

• C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O

• 6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂
