I recommend a science project that could test wind. Cut up a few flaps on a paper, try to make a mini windmill out of straws and thin cardboard, and study the difference between how much force you give it, and the wind it produces to move the paper flaps.

ATP is synthesized by substrate-level phosphorylation during which of the following?
pav-90 [236]

Answer:

C. only glycolysis and the Krebs cycle

Explanation:

Conversion of 1,3-bisphosphoglycerate into 3-phosphoglycerate and conversion of phosphoenolpyruvate into pyruvate during glycolysis obtains a total of 4 ATP molecules per glucose (2 from each reaction). Here, ATP formation occurs by the transfer of the phosphoryl group from a substrate such as 1,3-bisphosphoglycerate. Therefore, it is called a substrate-level phosphorylation.  

Similarly, oxidative decarboxylation of alpha-ketoglutarate into succinyl CoA and conversion of succinyl CoA into succinate forms 2 ATP molecules per glucose during Kreb's cycle. Here, the energy for ATP synthesis is provided by oxidative decarboxylation of a substrate. Therefore, it is also substrate-level phosphorylation.

Think of when pangea was a thing, when the continents were "all together". They moved apart, obviously, and they can fit like puzzle pieces. If that makes sense? Because they were once all together.
