Photosynthesis

What gas is released as a byproduct of photosynthesis?

• Carbon Dioxide

• Oxygen

• Nitrogen

• Methane

What is the function of RuBP in photosynthesis?

• RuBP is a 5-carbon sugar that combines with CO₂ to initiate the Calvin cycle.

• RuBP is a pigment that absorbs light energy for photosynthesis.

• RuBP is a protein that transports nutrients in plants.

• RuBP is a waste product of the photosynthesis process.

What is produced during the light-dependent reactions?

• ATP and NADPH

• Glucose and Oxygen

• Carbon Dioxide and Water

• FADH2 and Citric Acid

What are the two main stages of photosynthesis?

• Light-dependent reactions and light-independent reactions (Calvin cycle)

• Photosystem I and Photosystem II

• Glycolysis and Krebs cycle

• Electron transport chain and oxidative phosphorylation

What do plants need for photosynthesis?

• Oxygen

• Glucose

• Carbon dioxide

• Nitrogen

What is the primary pigment involved in photosynthesis?

• Chlorophyll

• Carotene

• Xanthophyll

• Melanin

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

• RuBisCo (Ribulose Bisphosphate Carboxylase)

• Phosphofructokinase

• Hexokinase

• Pyruvate Kinase

What is the role of water in photosynthesis?

• Water is used to absorb sunlight.

• Water provides electrons and protons for the light-dependent reactions and is split to release oxygen.

• Water acts as a nutrient for plant growth.

• Water helps in the formation of glucose.

Which organelle is responsible for photosynthesis?

• Mitochondria

• Ribosome

• Chloroplast

• Endoplasmic Reticulum

What is photolysis in the context of photosynthesis?

• The process of converting carbon dioxide into glucose.

• The process of splitting water molecules using light energy during the light-dependent reactions.

• The process of absorbing sunlight to produce energy.

• The process of releasing oxygen as a byproduct of respiration.
