Considering the ATP cycle, which of the following would have the most potential energy to perform work for cell activities? A. A
Mumz [18]

Answer:

ATP

Explanation:

We are well aware of the fact that ATP is considered to be the energy currency of the cell. If we talk about cell activities it needs an energy input. No doubt that H+ ions play an important role in electron transport chain step of the production of ATP, but the ultimate product which is used by the cell is ATP.

AMP and ADP are also energy sources but they contain less amount of energy as compared to ADP because in ATP there are three phosphate bonds and each bond upon breakage releases almost 7.3 kj/mol of energy. So it definitely will be more in ATP as compared to ADP and AMP.

Iteru [2.4K]
<span>United States: 0.308 quads/million people. Japan: 0.165 quads/million people. This is a simple matter of division. Take the total energy used and divide among the number of people using it. So: United States: 97.5 / 316.5 = 0.308056872 quads per million people. Japan: 21 / 127 = 0.165354331 quads per million people. Rounding to 3 significant figures gives 0.308 quads/million for United States and 0.165 quads/million for Japan.</span>

In which Colorado Rockies scenario was there more erosion? Why was there more erosion in the scenario? ANSWER ASAP PLSSSSS​
steposvetlana [31]

Answer:

There was more erosion in the Colorado Rockies scenario where there was steady rain compared to the scenario in the same area where there was only a drizzle. There is more erosion because the steady rain increased the volume of the river more than the drizzle did. Because there was more water added to the river, the river flowed faster. The faster a river flows, the more sediments it transports or erodes.
