ATP as the molecule that distributes energy within cells

Cellular respiration

a metabolic process that breaks down organic molecules to release energy to be used in cells

What is the intial source of energy

organic compounds

What organic compounds are used in cell respiration

carbohydrates, lipids and proteins

T/F: cellular respiration is the same as breathing

False

Breathing?

the intake of oxygen and release of carbon dioxide from the lungs

Cellular respiration?

controlled release of energy from organic compounds to make ATP

How much energy is transferred in cellular respiration

small quantities

Where is the energy transfered

to ATP in many small steps with little heat loss

What nucleotide is produced during respiration

Adenosine triposphate (ATP)

What does ATP fuel

many biological reactions

What properties make ATP suitable as an energy source

• chemical energy locked up in structure

• can be released in small managebale quantities (ATP to ADP)

• very reactive molecule

• small and can be moved easily into facilitated diffusion
