Active transport would be required because in order to move across a membrane against the concentration gradient, energy is needed. Active transport uses energy to help molecules/ ions achieve this movement.<span>

_____ is a regulatory mechanism in which the end product of a metabolic pathway inhibits an enzyme that catalyzes an early step
hjlf

Answer:

Option C) Feedback inhibition

Feedback inhibition is a regulatory mechanism in which the end product of a metabolic pathway inhibits an enzyme that catalyzes an early step in the pathway.

Explanation:

Feedback inhibition is a regulatory mechanism in which a biochemical pathway is regulated by the amount of the product that the pathway produces. Thus, it is also known as end-point inhibition.

For example:

The accumulation of ATP inhibits the action of phosphofructokinase, the enzyme that catalyzes the rate-limiting step of glycolysis

Many promoter regions in genes transcribed by eukaryotic RNA polymerase II do not contain a TATA box sequence. However, all thre
Evgen [1.6K]

Answer:

A. The DNA-bending function of TBP cannot be performed by another protein in the general transcription factor complex.

Explanation:

TATA  box sequence binding protein binds to aspecific region on DNA known as TATA Sequence. TATA binding protein binding to the DNA Sequence is necessary because it generates <em>bending of DNA till 80° angle.</em>

<em></em>

BINDING of all transcription factors depends solely upon the binding of TBP directly, that is why TATA binding proteins bonding to DNA is very important for initiation of transcription. Any other protein does not have the capacity of band formation with DNA. Hence, A. the DNA-bending function of TBP cannot be performed by another protein in the general transcription factor complex.

Suppose the moon rotated on its axis just as quickly as Earth. Would you still always see the same side of the moon from Earth?
Snowcat [4.5K]
Currently it takes about 27.3 days for the Mon to rotate full circle around it's axis. It takes about 27 days for the Moon to make full circle around the Earth. This is why we always see the same side of Moon.

If the Moon was rotating around it's axis as quickly as Earth it would mean that it takes about 24h to rotate. Currently, no matter where we stand on the Earth we can see the same side of Moon. If the Moon had 24h rotation period we would see different parts of Moon from different parts of Earth. We would see the entire surface of Moon. But, as the Moon and the Earth would have same rotation period from some point on Earth we would constantly see the same side of Moon.

Example: From Europe we would see one side, from North America other side and from Asia yet another side. But from Europe we would constantly see the same side of Moon.
