What changes in fatty acid metabolism would result from a mutation in the muscle carnitine acyltransferase I in which the mutant

protein has lost its affinity for malonyl-CoA but not its catalytic activity?
A. Fatty acid synthesis in the mitochondria and fatty acid oxidation in the cytosol could occur simultaneously.
B. Fatty acid synthesis in the cytosol and fatty acid oxidation in the mitochondria could occur simultaneously.
C. Synthesis of malonyl carnitine could only occur at high malonyl-CoA concentration.
D. Synthesis of malonyl-CoA would no longer be inhibited carnitine.

Answer:

<h2>B. Fatty acid synthesis in the cytosol and fatty acid oxidation in the mitochondria could occur simultaneously.</h2>

Explanation:

Carnitine acyltransferase I, is a mitochodrial enzyme also known as Carnitine palmitoyltransferase I (CPT1).

The acyl group is transferred to carnitine by the cytoplasmic form of the enzyme by Carnitine acyltransferase I

Malonyl coA would no longer inhibit fatty acid entry into the mitochondrion and beta oxidation, so there might be a futile cycle of simultaneous fatty acid synthesis in the cytosol and fatty acid breakdown in mitochondria.

Which statement is most accurate concerning how photosystem II compares to the electron transport chain (ETC) of mitochondria? I
nordsb [41]

The correct answer is: In both systems, ATP is produced by chemiosmosis.  

Both of the processes, photosynthesis and electron transport chain in mitochondria use chemiosmosis (movement of ions across a semipermeable membrane, down their electrochemical gradient) to produce energy or ATP (via ATP synthase). The movement of hydrogen ions across the thylakoid membrane in order to galvanize the production of ATP is equal to the movement of those ions across the inner mitochondria membrane. Electrons are accepted by NADPH in photosynthesis (but not FADH2 as in mitochondria).

Use a Punnett square diagram to show why, for each pregnancy, the chances of giving birth to either a boy or a girl are 50-50. E
ikadub [295]

Answer:

Because the offspring of a male and female are always going to be xx, xx, xy, or xy.

Explanation:

Remember that men have different reproductive chromesomes than women. Women have 2 x chromesomes(xx) while men have 1 x and 1 y(xy). These are given down to their offspring.

So we can write the this out in a punnet square as(link down below).

After you see the visual, you will find that the genotypes are xx, xx, xy, xy.

As I said above, women have sex chromesomes xx, while men have sex chromesomes xy. When you match the genotypes on the punnet square with the ones we know from men and women, we find that two of them match with men and two match with female.

So with this, we can conclude that 2/4 of offspring will always be male and 2 will be female. And as you well know 2/4 is 1/2 which is 50%.
