Photosynthesis and Cellular Respiration: Key Concepts and Processes

In what cell organelle does photosynthesis occur?

Chloroplasts

In what cell organelle does cellular respiration occur?

Mitochondria

What are the three things needed for photosynthesis?

Carbon dioxide, Water, Sunlight

What are the two products of photosynthesis?

Glucose, Oxygen

What are the two things needed for cellular respiration?

Glucose, Oxygen

What are the three products of cellular respiration?

Carbon dioxide, Water, Energy (ATP)

What things are recycled during photosynthesis and respiration?

Carbon, Hydrogen, and Oxygen atoms

What needs to enter the system to provide energy that becomes unusable as heat?

Sunlight/Solar energy

What happens to animals that are deprived of oxygen?

They cannot do aerobic cellular respiration and must do anaerobic respiration.

Why would a meteor impact causing dust to block sunlight lead to mass extinction?

Sunlight is needed for photosynthesis, and without it, the cycle of matter could not continue.

How do you use energy from sunlight when walking your dog?

The energy comes from photosynthesis in plants, consumed as glucose, and used in cellular respiration to produce ATP.

What is the relationship between photosynthesis and respiration?

Photosynthesis produces Oxygen and Glucose for respiration, while respiration produces Carbon Dioxide and Water for photosynthesis.

Is photosynthesis an energy-storing or energy-releasing process?

Energy-storing (endothermic) process.

Is respiration an energy-storing or energy-releasing process?

Energy-releasing (exothermic) process.

What are examples of Aerobic exerises?

Walking and dancing (creates 36 ATP for every molecule of glucose)

What are examples of Anaerobic exerises?

Sprinting and lifting weights (creates 2 ATP for every molecule of glucose)
