Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP), located in the same mitochondria, not nucleus.
But for option A, does the nucleus really translate genetic information into protein, isn't that the function of the ribosome
The question is asking: which of these is NOT a function of the nucleus.
So we are looking for the odd one out, the thing the nucleus does not do.
Let’s start with option A.
It says the nucleus translates genetic information for the manufacture of protein. This one sounds complicated, but what it is really talking about is protein synthesis. The nucleus stores DNA, and that DNA carries instructions for making proteins. The actual building of proteins happens in the ribosomes in the cytoplasm, but the nucleus is still involved because it sends out the instructions in the form of messenger RNA. So even though the wording is a bit tricky, this option is basically linked to the nucleus because it is the source of the instructions. So it is related and not the answer.
Now option B says the nucleus stores and carries hereditary information. This one is very straightforward. Hereditary information means traits passed from parents to offspring, like eye colour or blood group. That information is stored in chromosomes, and chromosomes are inside the nucleus. So this is definitely a correct function of the nucleus. No argument there.
Now option C is the important one. It says the nucleus is the reservoir of energy for the cell. This is where the trap is. The nucleus does NOT store energy. The part of the cell that deals with energy is the mitochondrion, not the nucleus. Mitochondria are called the “powerhouse of the cell” because they produce ATP, which is the cell’s energy currency. The nucleus has nothing to do with storing or producing energy. So this statement is wrong when it comes to the nucleus.
Now option D says the nucleus controls the life processes of the cell. This is correct. The nucleus controls everything because it contains the genetic material that tells the cell what to do, when to grow, when to divide, and how to function. So this one is a real function of the nucleus.
Now let’s step back and see the pattern clearly. Three of the options are connected to genetic control and instructions. One option suddenly talks about energy storage. That one does not belong at all.
So the correct answer is C.
mRNA translate genetic information into protein so i dont thing A is also a function of the nucleus
