10. The oxygen debt of a muscle represents excess oxygen consumed post- exercise in order to do all of the following EXCEPT? a. Replace oxygen stored on myoglobin in the muscle b. Convert lactic acid to glucose c. Replace depleted Creatine Kinase enzyme levels d. Restore Muscle ATP levels e. All of the above occur
Without oxygen, a cell: 1) will not break down glucose for energy O2) cannot use ATP 3) makes lactic acid O4) makes more ATP

A critical reaction in the production of energy to do work or drive chemical reactions in biological systems is the hydrolysis of adenosine triphosphate, ATP, to adenosine diphosphate, ADP, as described by the reaction ATP(aq) + H,O(1) ADP(aq) + HPO (aq) in a biological cell in which for which AG x = -30.5 kJ/mol at 37.0 °C and pH 7.0. Calculate the value of AG [ATP] = 5.0 mm, (ADP) = 0.10 mM, and [HPO) = 5.0 mM. AGrx =...

A critical reaction in the production of energy to do work or drive chemical reactions in biological systems is the hydrolysis of adenosine triphosphate, ATP, to adenosine diphosphate, ADP, as described by ATP(aq) + H2O(l) --> ADP(aq) + HPO4(aq) or which ΔG°rxn = –30.5 kJ/mol at 37.0 °C and pH 7.0. Calculate the value of ΔGrxn in a biological cell in which [ATP] = 5.0 mM, [ADP] = 0.50 mM, and [HPO42–] = 5.0 mM. Delta Grxn =
The excitation, contraction, and relaxation of skeletal muscle
require the use of ATP. Because only limited stores of ATP are
immediately available in muscle tissue, ATP must be continually
supplied if contractile activity is to continue.
Depending on the type of movement or exercise, one or more
pathways can be used to provide the most efficient way of supplying
the ATP.
