SCIENCE 8 CELLULAR RESPIRATION

It produces energy needed for cellular activities

It helps in photosynthesis

It stores genetic information

It provides structural support

To harness light energy from the Sun and convert it to chemical energy of sugar

To absorb oxygen from the air

To release carbon dioxide

To produce water for the plant

From sunlight

From water

From the air

From food

A nitrogen base (adenine)

A 5-carbon sugar (ribose)

Three phosphate groups

A fatty acid chain

Glucose

Glycerol

Fatty acid

Amino acid

Photosynthesis

Cellular respiration

Fermentation

Glycolysis

Aerobic respiration requires oxygen.

Anaerobic respiration occurs in the absence of oxygen.

Both types of respiration produce ATP.

Aerobic respiration does not produce ATP.

ATP, NADH, FADH2

CO2, H2O, NAD+

Glucose, Oxygen, Water

ADP, FAD, NAD+

NADH

FADH2

ATP

Glucose

They store energy for long-term use.

They act as electron carriers to generate ATP.

They break down glucose directly.

They transport oxygen in the cell.

NADH and FADH2

Glucose and Oxygen

Pyruvate and Water

ADP and Phosphate

It takes place in the inner mitochondrial membrane.

It is the only phase in glucose metabolism that uses atmospheric oxygen.

It produces water by reducing molecular oxygen.

It occurs in the cytoplasm.
