Photosynthesis and Respiration

Question 1

Photosynthesis

Answer 1

The process of photosynthesis converts light energy to chemical energy (glucose). The energy is stored in the chemical bonds of the glucose
molecules

Question 2

Photosynthesis word equation

Answer 2

Light energy
Carbon dioxide + water –> Carbohydrates + oxygen chlorophyll

Question 3

Photosynthesis chemical equation

Answer 3

CO2 + H2O –> C6H1206 +O2
6CO2 +6H2O –> C6H12O6 + 6O2

Question 4

Respiration

Answer 4

when glucose is broken down some of the chemical energy is released for
use in the cell.

• This process is known as respiration.

Question 5

Cellular Respiration Word Equation

Answer 5

Glucose + Oxygen —> Carbon Dioxide + Water + ATP

Question 6

Cellular Respiration Chemical Equation (Balanced)

Answer 6

C6H12C6 + 6O2 —> 6CO2 + 6H2O + ATP

Question 7

Aerobic Respiration

Answer 7

Respiration that occurs when oxygen is present and completely breaks down glucose.
Location: cytoplasm —> mitochondria
Efficiency: very high
Products: CO2 & H2O (Animals/Plants)

Question 8

Anaerobic Respiration (Fermentation)

Answer 8

Respiration that occurs when oxygen is NOT present and breaks down glucose.
Location: cytoplasm
Efficiency: Low (not fully broken down)
Products:
Animals - Lactic Acid C2H4OHCOOH
Plants - CO2 & Ethanol C2H5OH

Question 9

ATP (Adenosine Triphosphate)

Answer 9

Is the cell’s immediate source of energy, and it is used for most energy requiring process in the body.

Energy is released by breaking bonds between 2 phosphate units, producing ADP.
