Photosynthesis & Cellular Respiration (Lecture 17)

a process whereby plants, algae, and certain bacteria transform light energy into chemical energy, using carbon dioxide and water as starting materials and releasing oxygen gas as a by-product.

Photosynthesis (anabolic process)

Distance between two energy waves

Wavelength

Have structures that make them especially rich in chemical energy.

Carbohydrates, Fats, & Gasoline

Living cells and automobile engines use the ___ basic process to make the chemical energy stored in their fuels available for work.

Same

The first photosystem?

Water

The main way that chemical energy is harvested from food and converted to ATP energy. 

Cellular Respiration

This process means it just uses oxygen.

Aerobic process

Carbon Dioxide + Water —> sugar + oxygen

Photosynthesis (Anabolic process)

Oxygen + Sugar —→ Water + Carbon Dioxide

Cellular Respiration (Catabolic process) 

Requires Oxygen is what process? 

Aerobic Process

Happens inside of each cell.

Cellular respiration

All living things use ___ reactions to harvest that stored energy.

Catabolic

‘Lysis’

To cut 

Breaking apart of glucose is ___.

*Glycolysis

A series of reactions that extract energy from molecules, producing carbon dioxide and high-energy electron carriers. 

Citric Acid Cycle 

Fuel rich in chemical energy.

Glucose and oxygen

Waste products poor in chemical energy

Carbon dioxide and water
