Succinate dehydrogenase catalyzes the conversion of succinate to fumarate. The reaction is inhibited by malonic acid, which rese
natima [27]

Answer:

C. Succinate is the substrate, and fumarate is the product.

Explanation:

Succinate is the substrate of the enzyme Succinate dehydrogenase, and as a product is obtained fumarate.  In this scenario, malonic acid plays the role of a competitive inhibitor because its structure resembles the succinate's, so they compete for the active site of the enzyme.  So,  A option is wrong because fumarate is not the product. B option is wrong too because malonic acid is an inhibitor, not the substrate.  Also, D is incorrect because malonic acid is a COMPETITIVE inhibitor, not a noncompetitive one. Finally, E can´t be true because malonic acid is not product and fumarate is the product, not an inhibitor.

What main criterion determines major divisions in tje geologic time scale?
bagirrra123 [75]

Answer:

A) Times of major climate change

Explanation:

The geological time scale is based on major changes in Earth's climate history. This is because of the reason that climate governs the geological processes on Earth. In geology, we study the ages with the help of stratigraphical data where sediment deposition and the fossils it is hosting are the keys to understand the environmental conditions at that particular time. These conditions didn't change significantly unless the climate was changed. An example is the extinction of dinosaurs during K/T boundary event (mass extinction). The most likely reason is the hitting of a meteorite on Earth that changed the climate of Earth in a short period making it least favorable for many organisms to survive.

On the other hand, the occurrence of huge events cannot be used to establish a geological time scale because sometimes, the changes happen more slowly.

Similarly, shifts in the Earth orbits are cyclic however geological time scale doesn't reflect cyclic changes. The same climate can establish in different ages but these events are not used not as a criterion to establish a geological time scale.

In the end, the time span of humans on Earth is very small when compared with the overall geological time scale. Humans record exists from Pleistocene (2,580,000 to 11,700 years ago) to today whereas geological time scale starts in the Archean Eon (4.0 billion to 2.5 billion years ago).
