What is the effect of the following changes on the O2 affinity of hemoglobin?

Biology
1 answer:
Vladimir79 [104]3 years ago
3 0

Answer and Explanation:

The affinity of hemoglobin for Oxygen is controlled when the ligands H^{+} , CO_{2} and BPG binded.

The binding of every ligand moves the saturation curve of  Oxygen towards right—that is, the oxygen affinity of hemoglobin is decreased within the sight of ligand.  

(a) A pH drop will expand the oxygen affinity to myoglobin and decline the oxygen affinity for hemoglobin. This implies less oxygen will be taken by the lungs and more will be off stacked at the tissues diminishes the affinity.

(b) An abatement in the partial pressure of CO_{2} will expand affinity of oxygen to hemoglobin and diminishes the affinity of oxygen for myoglobin expands the affinity.

(c) An expansion in BPG levels diminishes the affinity of oxygen for hemoglobin and expands oxygen's affinity for myoglobin  diminishes the affinity.  

(d) As CO ties to a couple of subunits of a hemoglobin tetramer, the affinity for oxygen is expanded generously in the rest of the subunits. Subsequently, a hemoglobin tetramer with two bound CO particles can productively tie oxygen in the lungs—yet it discharges almost no of it in the tissues.

Examine the animal cells as they are each in a specific phase in their life cycle. Then, identify the phase and what is occuring
Sveta_85 [38]

The life cycle of an animal cell consists of two phases called interphase and mitosis.

The interphase is characterized by the moment in which the cell is in intense methadological activity. At this point, it is possible to see that the cell has increased in size and has become wider and more robust. This phase is divided into three sub-phases called G1, S and G2.

In subphase G1, it is possible to observe that the cell is causing the synthesis of RNA and proteins on a large scale,

In subphase S, it is possible to observe that DNA division is taking place.

In the G2 subphase, it is possible to visualize that the cell is forming microtubules of the mitotic spindle. In addition, RNA and proteins are produced, but in lesser quantities.

After interphase, mitosis begins, which is the period of cell division, where two daughter cells identical to the mother cell are generated. Mitosis has the following phases: prophase, prometaphase, metaphase, anaphase and telophase.

In the prophase, it is possible to notice that the chromosomes were duplicated and formed pairs of chromosomes (the sister chromatids). In this phase it is also possible to see the condensation of the promatin, the formation of the mitotic spindle and the disappearance of the nucleolos.

In the first phase, it is possible to visualize that the chromosomes have become condensed and are connected by the poles and not by the middle anymore. At this stage, the nuclear membrane also disappears.

In the metaphase, it is possible to visualize that the chromosomes move to position themselves in the cell equatorial plane (sister chromatids are still formed).

In anaphase, it is possible to visualize the separation of the sister chromatids, generating child chromosomes, which are separated and moved to opposite ends in the cell. At that point, the cell takes on an elongated shape. Child chromosomes form pairs and look the same as normal chromosomes.

In telophase, it is possible to visualize the formation of new nuclei at each end of the cell. The spindle microtubules are destroyed, the comosomes are decondensed and the cell is ready to be divided.

Anyone help me with this question plz
wolverine [178]

Hey again,

The answer you are looking for is B).

Just as proteins consist of long chains of amino acids, DNA and RNA consists of nucleic acid chains called nucleotide's. Nucleotide's are composed of three units: base, sugar (monosaccharide) and phosphate. Bases are found in both DNA and RNA. As seen below, they are adenine, cytosine, guanine, thymine, and uracil.

Hope this helps!!!!!!

Who or what comprised 3 or the parts: all living things are made of cells, cells are the basic unit of life, all cells come from
Sveta_85 [38]

Answer:

Cell theory

Explanation:

Cell theory is a universal theory proposed by three scientists namely: Theodor Schwann, Mathias Schleiden and Rudolf Virchow in the 1830's. The cell theory compose of three components:

- All living things are made up of one or more cells.

- Cells are the basic and fundamental unit of life

- All cells emanate from pre-existing cells.

Based on this question, these three components are what makes up the CELL THEORY.
