Answer:
Completely oxidize an acetyl group to carbon dioxide.
Explanation:
The net effect of TCA cycle is the oxidation of acetyl group so as to liberate carbon dioxide (CO₂). This oxidation of acetyl group is coupled to the reduction of hydrogen carriers like NAD⁺ and FAD so as to produce NADH + H⁺ and FADH₂ respectively. During TCA cycle, the acetyl CoA which is formed from pyruvate in PDH complex, transfers it's acetyl group to oxaloacetate which is a 4 carbon compound. As a result of this transfer, a 6 carbon compound known as citrate is formed. This citrate is then passed through a series of reactions during which it is broken down so as to regenerate oxaloacetate back. During these reactions, some very high energy molecules like NADH, ATP and FADH₂ are also produced.
Answer:
An important feature that B-cells must have in order to become plasma cells and synthesize antibodies is increased rough endoplasmic reticulum in order to have the surface area needed for antibody production (option A).
Explanation:
The transformation of B cells into plasma cells to produce antibodies is a well known function of lymphocytes related to the immune response. This leads to a series of structural transformations in order to performs their function.
The rough endoplasmic reticulum (RER) has the function of contributing to protein synthesis, in conjunction with the ribosomes that are attached to it and the information of the mRNA.
<em>One of the changes experienced by B cells in their transition to plasma cells is the availability of larger RERs, in preparation for antibody synthesis, formed mostly by proteins</em>.
