Answer:
Characteristics of Prokaryotic Cell
They lack a nuclear membrane.
Mitochondria, Golgi bodies, chloroplast, and lysosomes are absent.
The genetic material is present on a single chromosome.
The histone proteins, the important constituents of eukaryotic chromosomes, are lacking in them.
The cell wall is made up of carbohydrates and amino acids.
Explanation:
which equals nucleoid
Through mitosis, the number of chromosomes is kept constant from one cell generation to the next.
<h3>What occurs during mitosis?</h3>
A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes. Due to the importance of this procedure, specific genes carefully regulate each phase of mitosis. Health issues like cancer may develop when mitosis is improperly controlled.
<h3>How many phases of mitosis are there?</h3>
Prophase, pro metaphase, metaphase, anaphase, and telophase are these stages.
<h3>What function does mitosis serve?</h3>
Mitosis' purpose is to divide the genome so that the two daughter cells inherit an identical and equal number of chromosomes.
<h3>Where in the cell cycle does mitosis occur?</h3>
The mitotic phase, which consists of mitosis and cytokinesis and produces two daughter cells, begins after interphase. Despite the fact that the two processes frequently overlap, mitosis occurs before cytokinesis.

Is Complex III reduced or oxidized?
Process - During each two-cycle process, the modified Q cycle in Complex III reduces cytochrome c, oxidizes ubiquinol to ubiquinone, and transfers four protons into the intermembrane gap.
Does ubiquinone get oxidized or reduced?
- At the cellular level, CoQ10 exists as a redox pair, or in two forms that alternate back .
- Forth as CoQ10 transfers a hydrogen in the mitochondria's electron transfer chain: ubiquinone, which is the oxidized form, and ubiquinol, which is the reduced form.
What is the function of complex III?
- The mitochondria of cells, which transform the energy from food into a form that cells can utilise, are where Complex III is found.
- Cells obtain a great deal of their energy from a process called oxidative phosphorylation, which is carried out by a number of complexes, including Complex III.

<u>The complete question is -</u>
We now get to the crux of the matter. If we are to identify which step is blocked, we will need at least two specific pieces of information.
Now let's put it all together . If you were told that ubiquinone was reduced but cytochrome c was oxidized , you would know that the pathway was blocked somewhere between these two carriers , but you would not necessarily know whether the block was at the ubiquinone ⇒ Complex lll step or the Complex III ⇒ cytochrome c step.
To differentiate between these two steps, you add an unknown inhibitor to a suspension of rapidly respiring mitochondria. After subjecting the suspension to MAGIC analysis, you find that there is an accumulation of reduced ubiquinone and that Complex III is oxidized.
