Answer:
DNA is nucleic acid
Explanation
The correct answer here is "cell membrane". Generally it makes sure that nothing enters or leaves the cell, except by its highly guarded "gates", such as ion channels, that let some particles through - but they're very picky about whom to let in!
Here's a few: magnesium, oxygen, silicon, phosphate, and aluminum are all found in earth's crust in high proportion. oxygen being the highest proportion of any other element.
Answer:
The correct answer is:
a)FADH2
c)GTP
e)NADH
Explanation:
The Citric acid cycle(TCA) also known as the <em>Kreb cycle,</em> is a focal metabolic center of the cell. It is a sequence of chemical reactions in which the acetyl portion of acetyl CoA is degraded to carbon dioxide and hydrogen atoms.These reactions all occur in the matrix of the mitochondria. This cycle is also an important source of precursor for other molecules such as amino acids, nucleotide bases cholesterol etc. The function of the citric acid cycle is the gathering of high-vitality electrons from carbon fuels. The citric acid cycle removes electrons from acetyl CoA and use it to reduce NAD and FAD into NADH2 and FADH2 respectively.
<em>Overall, The citric acid cycle oxidizes two carbon units(from acetyl CoA) and produces two molecules of carbon dioxide, one molecule of GTP and high energy electrons which are present in the form of NADH2 and FADH2</em>
