Answer:

What determines the amino acid sequence of a protein is the sequence of nitrogenous bases in DNA.

Explanation:

We know that proteins, substances essential for the functioning of the body, are a set of amino acids that are linked together by peptide bonds. The amino acid sequence of a protein will be determined by the arrangement of nitrogenous bases in an mRNA. This, in turn, will be produced from a DNA molecule. We can say, therefore, that DNA provides the information for the production of proteins.

The genetic code can be defined as the relationship between the cracks (codons) found in the mRNA and the amino acids found in a protein. Codons are cracks formed by nitrogenous bases (A, U, C and G).

The four nitrogenous bases can have 64 different combinations, therefore, there are 64 different codons. Of these codons, 61 will encode the 20 different types of existing amino acids. The other three codons (UAA, UAG and UGA) will be responsible for indicating the places where the synthesis ends, and are also called stop codons. They do not encode any amino acids and are not read by tRNA, but by proteins called release factors.

Which pharmacokinetic parameter is affected most by decreased intestinal motility related to the aging process? a. excretion b.
Tpy6a [65]
I believe the answer is <span>c. absorption

</span>The phase of pharmacokinetic that happens in the intestine is when the drug absorbed. A person with old age will have lower intestine motility. This will increase the transit time which will increase the amount of drug absorbed.

Age could also influence others pharmacokinetic parameter(<span>excretion, distribution, metabolism) but it is related with another organ, not intestine.</span>

In addition to transporting oxygen from the lungs to the tissues, hemoglobin is also involved in transporting carbon dioxide fro
neonofarm [45]

The correct option is (C) Carbon dioxide reacts with an amino group to stabilize the deoxyhemoglobin state.

In addition to transporting oxygen from the lungs to the tissues, hemoglobin is also involved in transporting carbon dioxide from the tissues to the lungs where, Carbon dioxide reacts with an amino group to stabilize the deoxyhemoglobin state.

<h3>How does hemoglobin contribute to the movement of carbon dioxide from the tissues to the lungs?</h3>
  • The transport of carbon dioxide in the blood is influenced by a number of factors. First, blood contains more carbon dioxide soluble molecules than oxygen. The plasma contains 5–7% of the total dissolved carbon dioxide.
  • Second, carbon dioxide can enter red blood cells and bind to hemoglobin or it can bind to plasma proteins. In this form, 10% of the carbon dioxide gets transported.
  • A substance known as carbaminohemoglobin is created when carbon dioxide binds to hemoglobin. Hemoglobin and carbon dioxide can bind to one other again.
  • As a result, when it gets to the lungs, the carbon dioxide can separate from the hemoglobin without restriction and leave the body.
  • Third, the bicarbonate buffer system is responsible for transporting 85% of the carbon dioxide molecules.

I understand that the question you are looking for is "In addition to transporting oxygen from the lungs to the tissues, hemoglobin is also involved in transporting carbon dioxide from the tissues to the lungs. How is this accomplished?

A. Carbon dioxide competes for the oxygen-binding site on the heme.

B. Carbon dioxide competes for the 2,3-BPG-binding site.

C. Carbon dioxide reacts with an amino group to stabilize the deoxyhemoglobin state.

D. Carbon dioxide binds to the carboxyl terminus of hemoglobin."
