Answer:
There are difference in the TCA cycle of both prokaryotes and eukaryotes. In prokaryotes mitochondria is absent of TCA occurs in the cytosol. In eukaryotes it occurs in the mitochondria.
<span>In this pathway, an NADP-dependent enzyme </span><span>catalyzes the dehydrogenation of </span><span>D-threo-isocitrate</span><span> to </span>2-oxoglutarate<span>, while eukaryotes employ an NAD+-dependent enzyme</span><span>. Another difference is that while in most eukaryotes the conversion of </span><span>(S)-malate</span><span> to </span>oxaloacetate<span> is catalyzed only by an NAD-dependent enzyme, p</span><span>rokaryotes that employ this variation of the TCA cycle possess an alternative quinone-dependent enzyme.</span>

Answer:
D
Explanation:
Atomic radius is the distance from the atom's nucleus to the outer edge of the electron cloud. In general, atomic radius decreases across a period and increases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant.
