Large slimy blue-green algae (BGA) blooms have been found in Lake Okeechobee and waters flowing downstream. Florida’s government wants to strengthen water quality policies to address this issue. You are an environmental health specialist that has been asked to use your scientific expertise to testify in front of the State Legislature as to why they should vote to pass the recent bill.
In your testimony, you need to define what BGA is, its effect on the environment, and its health effects on humans and animals. Explain the factors that cause BGA blooms, and what factors continue their spread. Using each of the four major components to be considered in policy development (harm, risk, impacts, and social costs), discuss how the new water policies will affect the social and economic health of Florida.

Although not part of glycolysis,
endogenous stores of phosphocreatine in skeletal muscle are
suggested to provide a reserve of ATP through substrate-level
phosphorylation, as shown below:
a) Phosphocreatine + H2O ? Creatine + Pi + 10.3 kcal/mol
b) ADP +
Pi + 7.3 kcal/mol ? ATP + H2O
Add these two reactions together (including the energy terms) to show the net, coupled reaction

Food labels list that a gram of fat has 9 kcal of energy and that a gram of carbohydrate (or protein) has 4 kcal of energy. A mass to mass comparison, however, is misleading. A better comparison is mol to mol, which corrects for differences in MW. This can be done by comparing a molecule of glucose, which has 6 carbons, to a molecule of a fatty acid that also has 6 carbons.Complete the missing entries in the following table for the complete oxidation of one molecule of caproic acid in skeletal muscle. Caproic acid is a 6-carbon saturated, medium chain fatty acid found naturally in various animal fats and oils. (Caproic acid undergoes two cycles of ?-oxidation to form three acetyl-CoAs).
