ATP – adenosine triphosphate. UNIVERSAL ENERGY CARRIER.

Sources of energy

ATP – adenosine triphosphate. UNIVERSAL ENERGY CARRIER.

ATP carries the energy to power EVERY reaction and process in ALL living things.

Sources of energy

ATP – adenosine triphosphate. UNIVERSAL ENERGY CARRIER.

ATP carries the energy to power EVERY reaction and process in ALL living things.

It is then charged up by food molecules – this process is called cellular respiration.

One molecule of glucose charges up 38 molecules of ATP.

ADP – adenosine diphosphate and ATP are similar.

ATP

ADP – adenosine diphosphate and ATP are similar.

ATP carries the energy whereas ADP is the empty carrier.

ATP

ADP – adenosine diphosphate and ATP are similar.

ATP carries the energy whereas ADP is the empty carrier.

The last phosphate bond is the high energy bond.

ATP carries the energy whereas ADP is the empty carrier.

The last phosphate bond is the high energy bond.

This bond is where energy is carried.

ATP

ADP – adenosine diphosphate and ATP are similar.

ATP carries the energy whereas ADP is the empty carrier.

The last phosphate bond is the high energy bond.

This bond is where energy is carried. When ATP (tri) gives up its energy, it loses a

phosphate and turns into ADP (di).

phosphate and turns into ADP (di). ADP then goes back to the cytoplasm and

mitochondria to be recharged.

Most of the energy to charge up ADP to ATP comes from the hydrogen in glucose.

More carriers - NAD

CO2 formed as a waste product is breathed out.

Hydrogen needs to be carried to the correct place – this is where NAD comes in!

NAD is when it is empty – and NADH2 is when there is hydrogen (see! The H gives it away…)
