Psychographic segmentation includes separating your market into fragments in view of various identity characteristics, values, states of mind, premiums, and ways of life of purchasers. This division is beneficial in light of the fact that it enables you to participate in item plan and showcasing in an engaged way.
Answer:
A red blood cell, sitting in the right atria of the heart is chocolate-brown in color since its a deoxygenated red blood cell with carbon dioxide rather than oxygen in its hemoglobin.
First
The tricuspid valve pumps it through the right ventricle
Secondly
pulmonary valve pumps it from the right ventricle to the pulmonary circulation.
Then
In the alveoli of the lungs, gas exchange occurs during pulmonary circulation
The end product is oxyhemoglobin( bright red colour) I.e oxygenated blood
The next step
pulmonary veins is the means whereby the red blood cell go to the left atria from the pulmonary circulation through the aortic valve
to mitral valve then to the aorta and systemic circulation
Therefore
oxygen is replaced by carbon dioxide during systemic circulation indicating a end to cellular respiration
Lastly
It's transported back to the right atrium of the heart completing the cardiac cycle.
Answer:
The correct option is D.
Explanation:
Protein generally are very sensitive macro molecules; they have specific temperatures and pH that are ideal for their operations, this is especially true for proteins that act as enzymes in biochemical reactions.
There are four different types of structures that a protein can assume, these are primary, secondary, tertiary and Quaternary structure. The structure of a protein determines the kind of function it can perform.
There are some factors that can destroy the structure and functions of proteins, these include excessive heat and pH. A protein is said to be denatured when its secondary and tertiary structure have been disrupted or destroyed. Denaturation does not affect the primary structure of the protein, thus, the peptide bond remains intact.
Denaturation is usually temporary and can be reversed if the factors that cause denaturation is removed, this process is called RENATURATION. Renaturation process allow the protein to refold and resume its functions. But sometimes, denaturation can be permanent and irreversible leading to permanent loss of protein functions.
Answer:
D) It is a coordinator of the processes of glycolysis and the Krebs cycle.
Explanation:
Phosphofrutokinase is a very important enzyme in glycolysis, as it acts as a regulating factor of the glycolytic process that catalyzes a phosphorylation: the conversion of fructose 6-phosphate and ATP into fructose 1,6-bisphosphate and ADP. This is an allosteric enzyme, which is activated by citrate and ADP, but is inhibited by the presence of ATP that endorses the enzyme that its work is not needed at the moment. Although very important in glycolysis, this enzyme is not part of the krebs cycle.
