many of these tests are subjective, the actual correct answer may be what they are looking for. i can offer a little help

number 3 i am SURE is a phophate group. ATP is adenosine triphosphate, after ATP is used for energy there is ADP, or adenosine diphosphate left over. phosphocreatine will donate a phophate group to ADP to regenerate ATP. this is why supplementing with creating gives extra endurance.

number 5 is Hydration status and fat mass. calipers squeeze subcutaneous fat. a lot of that 'fat' is actually stored water. try taking a STRONG diuretic, look in the mirror the next day. look where you store fat and squeeze it. its reduced greatly - obviously you didnt melt all your fat overnight, you lost a lot of water. this difference in 'sqeezed fat' is what the caliper measures - thus error introduced depending upon hydration level.

number 6 if by oxidative system they are referring to one of the 3 main major energy systems in the human body that yield ATP - phosphagen system, glycolytic system, and oxidative phosphorylation. oxidative phosphorylation produces much more energy than the other two, therfore i would say the answer is d. It provides very large quantities of ATP for energy

number 7 Anaerobic glycolysis is very inefficient compared to oxidative phosphorylation, 18 times less energy. it only can produce energy for very short peroids of time. unfortunately the answers given are so close in length i bet 50 different experts in metabolism would give different answer. sorry bro if i had to guess i would pick a) 10-15 sec

number 9 is physical

number 11 - a monosaccharide is the simplest form of carb, therefore by elimination the answer is c. Starches and dietary fiber

number 12 IS ALL WRONG - typical of these types of tests. ATP does not contain "high-energy bonds". there is nothing special about the chemical bonds, including the phosphate bonds, in ATP. as with all chemical bonds, energy is required to break the bonds in ATP and energy is not released from breakage of these bonds. the bond-breaking in ATP requires initial energy input as does bond-breaking in all chemical reactions, but in the hydrolysis of ATP this input is more than re-paid with the energy of formation of 'hydration' bonds between the products (ADP + phosphate) and water. in other words, the hydration process for the phosphate products results in a release of energy that exceeds the amount of energy for breaking the phosphate bonds in ATP, hence resulting in a gain in a net energy release from these two reaction steps. anyways the answer is a.) High energy phosphate bonds

13 is a.) ATP-Phosphocreatine, glycolysis, oxidative - already explained above

14 is d.) A and B

Awesome, thanks guys

people keep replying that mechanical is not a form of energy. this is the INCORRECT answer.

heat - refers to thermal energy - energy that manifests itself as an increase of temperature, it is also the sum of sensible heat and latent heat

electrical - refers to electric charges, magnetic fields, and photons

mechanical - mechanical energy describes the sum of potential energy and kinetic energy present in the components of a mechanical system

there is no such thing as physical energy
