Back in the 1930s, a chemical called DNP (2,4-Dinitrophenol) was prescribed as a weight loss pill. Describe how DNP is a metabolic poison , and why it was thought to be a good mechanism for weight loss?

What is glycolysis? What are the products of this process?

1)  An average middle-aged person weighing 90 kg (200 lb.) contains 15 % body fat stored in adipose tissue. a) Calculate the amount of energy stored as fat in this person in kilojoules, assuming that energy yield from fat is 37 kJ/g. b) If this same amount of energy were stored in hydrated glycogen rather than fat (hydrated glycogen has an energy yield of 6 kJ/g), how much would the person weight in kilograms and in pounds?

Glycogen is the major animal storage polysaccharide, and is a polymer of glucose. a) List ALL the biochemical steps involved in storing GLUCOSE as glycogen b) Give NAME/S of the ENZYMES involved in EACH listed step c) What PULLS the reaction forward? d) Give the NAME of the tissue where these steps occur. (HINT: remember glycogen is branched chain).
