Slide 1

ADP, ATP and Cellular Respiration

ADP, ATP and Cellular Respiration

Slide 2

What Is ATP?

What Is ATP?

Energy used by all Cells

Adenosine Triphosphate

Organic molecule containing high-energy Phosphate bonds

Slide 3

Chemical Structure of ATP

Chemical Structure of ATP

3 Phosphates

Ribose Sugar

Adenine Base

Slide 4

What Does ATP Do for You?

What Does ATP Do for You?

It supplies YOU with ENERGY!

Slide 5

How Do We Get Energy From ATP?

How Do We Get Energy From ATP?

By breaking the high- energy bonds between the last two phosphates in ATP

Slide 6

What is the Process Called?

What is the Process Called?

HYDROLYSIS (Adding H2O)

H2O

Slide 7

How Does That Happen?

How Does That Happen?

ATPase

An Enzyme!

Slide 8

How is ATP Re-Made?

How is ATP Re-Made?

The reverse of the previous process occurs.

Another Enzyme is used!

ATP Synthetase

Slide 9

The ADP-ATP Cycle

The ADP-ATP Cycle

ATP-ase

ATP Synthetase

Slide 10

When is ATP Made in the Body?

When is ATP Made in the Body?

During a Process called Cellular Respiration that takes place in both Plants & Animals

Slide 11

Cellular Respiration

Cellular Respiration

Includes pathways that require oxygen

Glucose is oxidized and O2 is reduced

Glucose breakdown is therefore an oxidation-reduction reaction

Breakdown of one glucose results in 36 to 38 ATP molecules

Slide 12

Overall Equation for Cellular Respiration

Overall Equation for Cellular Respiration

6CO2 + 6H20 + e- + 36-38ATPs

C6H12O6 + 6O2

YIELDS

Slide 13

What Type of Process is Cellular Respiration?

What Type of Process is Cellular Respiration?

An Oxidation-Reduction Process or REDOX Reaction

Oxidation of GLUCOSE --> CO2 + H2O (e- removed from C6H12O6)

Reduction O2 to H2O (e- passed to O2)

Slide 14

What Carries the Electrons?

What Carries the Electrons?

NAD+ (nicotinadenine dinucleotide) acts as the energy carrier

NAD+ is a coenzyme

Its Reduced to NADH when it picks up two electrons and one hydrogen ion
