Answer questions in the handout

How many molecules in our body are central to converting the nutrients we gain from eating our food and transforming them into a form of energy our bodies can use readily?

• 1 • 10 • 100 • 1000 Answer: 1 = ATP, the currency of life

The ability to do work. All activities require energy.

› Kidney function› Liver function› Heart

Adenosine Triphosphate› Stores energy› Contains

Adenine Ribose = sugar Phosphate

› Connected by a HIGH energy phosphate bond

T = Tri = 3 phosphates ADP = D = Di = 2

phosphates

A-P-P-P = Energy Stored! A-P-P = ADP = Energy

Released You break a phosphate

and you release energy!
