Some proteins do indeed need assistance during the folding process. the general term used for the proteins that help other proteins fold is Chaperones.

<h3>What are Chaperones?</h3>
  • Chaperones are proteins that help big proteins or macromolecular protein complexes fold or unfold conformationally. There are different groups of molecular chaperones, all of which have the same purpose: to help big proteins fold properly during or after synthesis as well as following partial denaturation.
  • Protein translocation for proteolysis involves chaperones as well. The bulk of molecular chaperones aid in protein folding by binding to and stabilizing folding intermediates up until the polypeptide chain is entirely translated, rather than providing any steric information for protein folding.
  • Based on their target proteins and location, chaperones have different unique modes of operation.

The rate of kidney filtrate formation would normally be dependent upon all of the following factors except __________.
Wewaii [24]

Answer:

The correct option is BLOOD CALCIUM LEVEL.

Explanation:

The options attached to this question are given below:

A. Filtration membrane integrity

B. Systemic blood pressure

C. Blood calcium level

D. Renal artery/arteriole diameters

Kidney is an excretory organ, which functions by filtering waste products out of the blood. The rate at which the kidneys filter the blood depend on some factors; such factors include: water intake, systemic blood pressure, vasoconstriction, dehydration, filtration membrane integrity etc.

Blood calcium level does not have any effect on the rate at which the kidneys filter the blood.

Most organisms in the fossil record no longer live on Earth. What does this
forsale [732]

Answer:

Explanation:

The fossil record

This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones. Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth.

What does electronegativity means
Anna [14]
In Science, a electron in an atom is always negative. The more electrons you have, the more negative a atom is. The more protons (Positives) you have, the more positive a atom is. To balance an atom out, have the same amount of Electrons and Protons.
