Photosynthesis

What is the pigment in chloroplasts that performs photosynthesis?

• Chlorosynthesis
• Chlorophyll
• ADP
• Electron Transport

The interior space of the chloroplast is called:

• Lamellae
• Grana
• Stroma
• Thylakoids

Where does the light independent reaction take place?

• Matrix
• Stroma
• Thylakoid membrane
• Cytoplasm

Which of the following equations represents the overall chemical reaction for photosynthesis?

• 6O₂+ 6H₂O → C₆H₁₂O₆+ 6O₂

• C₆H₁₂O₆ + 6H₂O→ 6O₂+ 6O₂

• 6CO₂+ 6H₂O→ C₆H₁₂O₆+ 6O₂

• 6O₂ + 6H₂O→ C₆H₁₂O₆ + 6CO₂

The rate of photosynthesis can be influenced by...

• Temperature

• Carbon dioxide levels

• Light intensity

• Oxygen concentration

Temperatures that are too high can slow photosynthesis because

• stomata stay open

• enzymes are ruined

• there is not enough CO2

• there is too much water

Which of the following light color is absorbed by plants?

• Red

• Green

• yellow

• Light green

•An enzyme that fixes carbon from atmosphere to convert it to complex macromolecule glucose.

• RuBP (Ribulose bisphosphate)

• RuBisCo (Ribulose Bisphosphate Carboxylase)

• PGA (3-Phosphoglycerate)

• G3P (Glyceraldeyhyde 3-Phosphate)

What are the two products of the light reactions that are needed for the calvin cycle?

• NAD and NADPH
• NADP + and Glucose
• NADPH and ATP
• Oxygen and NADPH

Glucose is a ...

• sugar
• carbohydrate
• source of quick energy
• all are correct
