• Light-dependent reactions

• Glycolysis

• Krebs cycle

What is the initial substrate for glycolysis?

• Pyruvate

• Glucose

In the electron transport chain, what is the final electron acceptor?

• Oxygen

• Carbon dioxide

• ATP

• Glucose

Which pathway does anaerobic respiration include?

• Calvin Cycle

• Krebs cycle

• Lactic acid fermentation

• Photosynthesis

How are photosynthesis and cellular respiration interrelated at the chemical level?

• They both produce oxygen as a byproduct.

• The products of one process are the reactants of the other.

• They both consume ATP as their main energy source.

• They occur in the same organelle within a cell.

At the ecological level, how do photosynthesis and cellular respiration contribute to energy flow and nutrient cycles?

• By converting light energy into chemical energy and then into kinetic energy

• By producing oxygen for industrial use

• By maintaining the oxygen and carbon dioxide balance in the atmosphere

• By facilitating the water cycle

Which part of the chloroplast contains the chlorophyll necessary for the light-dependent reactions of photosynthesis?

• Stroma

• Thylakoid membrane

• Outer membrane

• Granum

What is the main purpose of ATP in cellular processes?

• To act as a pigment for coloration

• To serve as the primary cellular energy currency

• To store genetic information

• To facilitate passive transport
