 “The outer energy levels are full, but that doesn’t mean the inner ones are,” says a friend. How would you respond?
Anton [14]

He is WRONG

Explanation:

Any atom at the ground state has its orbital levels fill from the bottom (close to the nucleus) – up. The inner orbitals are of lower energy state and fill first because the atoms ‘likes’ to exist in the low energy and more stable state. Only when the atom is in an excited state do some of the electrons in the lower orbital levels shift to higher unfilled orbitals.

A is a DNA sequence where RNA polymerase binds and begins the process of transcription. A is a DNA sequence that binds regulator
WARRIOR [948]

<u>Answer:</u>

A is a DNA sequence that binds regulatory proteins that interact with promoter-bound proteins to activate transcription.

<u>Explanation:</u>

Background Knowledge:

DNA contains genes which is a particular segment of DNA. A gene usually has regulatory regions and a structural region.

Promoter: The regulatory region located to the 5 prime end of coding strand of the gene which is called as promoter that controls the binding RNA Polymerase during transcription.

The Terminator is the other regulatory region, located to the 3 prime end of coding strand of the gene. The terminator region causes RNA polymerase to stop transcription.

Structural region is the region present between the promoter and terminator.

Answer of the question is:

A is a DNA sequence that binds regulatory proteins that interact with promoter-bound proteins to activate transcription.

A) explain what would happen to atp production in a mitochondrion that has "leaky membranes", which would allow protons to diffu
ratelena [41]

B) In the process of the citric cycle that occurs in the mitochondrial matrix, electrons from this chemical pathways move from one protein complex to another and are ultimately accepted by oxygen molecule in the formation a water molecule. Concomitantly, protons are transported to the intermembrane space. Accumulation of H+ ions in the mitochondrial membrane creates an electromotive force that is harnessed by ATP synthase to enable the phosphorylation of an ADP to ATP.


A)     A leaky membrane, therefore, would interfere with the accumulation of protons in the intermembrane space. This will reduce the electromotive force that is harness by the ATP synthase to produce ATP by phosphorylation of ADP. Consequently, this defective mitochondria will produce less ATPs than a healthy mitochondria.
