Hemoglobin consists of four globular proteins, each formed from a polypeptide chain. Each globular protein contains a nonprotein

group with an iron ion. This iron ion binds to an oxygen molecule. Thus, every hemoglobin protein can bind four oxygen molecules. Select the correct statement about oxygen transport below.
A. Myoglobin transports oxygen through the bloodstream to tissue.
B. To carry oxygen, iron must be in its nonheme form.
C. Erythrocytes contain abundant myoglobin for transporting oxygen.

ollegr [7]

Cysteine contributes to the three-dimensional structure of a protein by forming covalent bonds with an identical amino acid in another part of the protein.

<h3>What is the Cysteine Structure?</h3>
  • Covalent disulfide bonds form between the sulfhydryl (-SH) groups of cysteines in different parts of a protein are very important in determining the three-dimensional shape of the protein.
  • is a HOOC-CH-(NH2)-CH2-SH proteinogenic amino acid that is semi-essential. Cysteine's thiol side chain frequently functions as a nucleophile in enzyme processes.
  • The sign Cyz is occasionally used when a deprotonated catalytic residue is present.
  • The sign Cym can also be used to usually denote the deprotonated form.
  • The thiol is capable of being oxidized to produce the disulfide derivative cystine, which is crucial for many proteins' structural integrity. Cyx is sometimes used in this context. It carries the E identifier E920 when added to food.
  • The codons UGU and UGC encode the amino acid cysteine.
  • Cysteine and methionine, which contain sulfur, are more quickly oxidized than other amino acids.

The sympathetic division of the autonomic nervous system prepares the body for stressful situations that require energy expendit
k0ka [10]

Answer:

True

Explanation:

The sympathetic autonomic nervous system activates the body for hormonal or neuronal responses also known as fight- or - flight response, For example during an fire emergency and there is a need to run. The response occurs primarily by  via impulses transmitted through the sympathetic nervous system, and also secondarily  through catecholamines secreted from the adrenal medulla.

Although the sympathetic autonomic nervous system is activated in stressful conditions, it needs to be constantly active even at a basal level to maintain homeostasis.

Why are clouds so flat from the bottom and so fluffy at the top?
mixer [17]

Because air pressure decreases at the rate of 0.91 inches per 1,000 feet of ascent, rising air expands and cools. The flat bottom of cumulus clouds defines the exact height at which a critical combination of temperature and air pressure causes water vapor within the rising current to condense into a visible cloud
