ATP & Respiration

Word equation of aerobic respiration

Oxygen + Glucose —> Water + Carbon dioxide

Word equation for anaerobic respiration?

Glucose —> Lactic acid

What is adenosine triphosphate made of?

Adenine, ribose (adenosine) & 3 phosphate

How is energy transferred?

Energy is converted from one form to another, food contains chemical energy where respiration breaks down glucose C-H C-C C-O bonds, and energy is transferred from respiration to ATP and heat

Why is ATP described as a universal energy currency?

Used for all living organisms and used to provide energy for all cell reactions

How is ATP synthesised and broken down

Synthesise ( ADP + Pi → ATP) Breakdown ( ATP → ADP + Pi)

Advantages of using ATP as an energy carrier (not store)

Only 1 enzyme needed in the breakdown of ATP, releases small amounts of energy so less energy wasted.

How much energy does ATP breakdown release?

30.6 KJ mol-1

What enzyme catalyses ATP? What’s the process?

ATPase catalyses ATP 3rd Phosphate (dephosphorylation)

TASK - draw and label both mitochondria and chloroplast as well as respiratory enzyme ( show direction)

Mitochondria - matrix, loop of DNA, Cristae, inner membrane, inter membrane space, outer membrane, 70s ribosomes, direction of stalked particle into matrix

Chloroplast - outer membrane, inter membrane space, inner membrane, stroma, thylakoid (membrane, space), granum, direction of stalked particle out of thylakoid into stroma

What enzyme do stalked particles contain?

ATP synthetase
