Where does the Krebs cycle take place in the cell?

• Endoplasmic reticulum

• Nucleus

• Cell membrane

• Mitochondria

Answer explanation

The Krebs cycle takes place in the mitochondria. It is a key process in cellular respiration, where energy is generated from the breakdown of glucose.

What is the overall equation for photosynthesis?

• 6CO2 + 6H2O → C6H12O6 + 6O2

• 6CO2 + 6H2O + ATP → C6H12O6 + 6O2

• 2CO2 + 2H2O + light energy → C6H12O6 + 2O2

• 6CO2 + 6H2O → C6H12O6 + 6O2

Answer explanation

The overall equation for photosynthesis is 6CO2 + 6H2O → C6H12O6 + 6O2. This equation represents the conversion of carbon dioxide and water into glucose and oxygen through the process of photosynthesis.

What is the overall equation for cellular respiration?

• Glucose + Oxygen -> Carbon Dioxide + Water + ATP

• Oxygen + Water -> Glucose + Carbon Dioxide + ATP

• ATP + Carbon Dioxide -> Glucose + Oxygen + Water

• Glucose + Carbon Dioxide -> Oxygen + Water + ATP

Answer explanation

The overall equation for cellular respiration is Glucose + Oxygen -> Carbon Dioxide + Water + ATP. This equation represents the process by which cells convert glucose and oxygen into carbon dioxide, water, and ATP, which is the energy currency of the cell.
