Photosynthesis and Respiration Review

Photosynthesis & Cellular Respiration Review

Photosynthesis & Cellular Respiration are processes that are part of the Carbon cycle

Photosynthesis & Cellular Respiration

• Reactants of one process....

• ... are the products of the other process

Multiple Choice

What are the products of Photosynthesis?

• water and ATP

• carbon dioxide and water

• glucose and oxygen

• oxygen and water

Multiple Choice

What are the products of Aerobic Cellular Respiration?

• Carbon dioxide, water and ATP

• Oxygen, glucose, and ATP

• ATP, oxygen and water

• Carbon dioxide, oxygen and glucose

Energy renewal

• Energy captured from sunlight by photosynthetic organisms is used and released in the cellular respiration of living things

• The energy that living things use, must continually be renewed through photosynthesis

Why is Photosynthesis so important?

• We must obtain glucose from plants

• Plants are the first step in the food chain

• The oxygen released during photosynthesis is necessary for many organisms.

Cellular Respiration

• Once solar energy is converted to chemical energy by photosynthesis, it has to be changed to a form that can be used by the organism

• Cellular respiration is the process that releases energy by breaking down food molecules in the presence of oxygen

Photosynthesis vs Cellular Respiration

Notice the order:

Photosynthesis - ETC then Calvin Cycle

Cellular Respiration - Kreb's Cycle then ETC

Photosynthesis vs Cellular Respiration

• Photosynthesis stores energy into glucose - Cellular Respiration releases energy from glucose

• Photosynthesis removes carbon dioxide and respiration returns it
