With an electromagnet, you can control the magnet strength and the magnetic force is stronger than a regular magnet.
Answer:
reduce NAD+ and FAD.
Explanation:
In the Krebs cycle the carbons donated by the acetyl group are oxidized to CO2 and the electrons pass to the electron transporters. As in glycolysis, a specific enzyme is involved in each step. Coenzyme A is the link between the oxidation of pyruvic acid and the Krebs cycle. In the course of these steps, some of the energy released by the oxidation of the CH and CC bonds is used to convert ADP to ATP (one molecule per cycle), and part is <u>used to produce NADH and H + from NAD</u> (three molecules per cycle). In addition, <u>a fraction of the energy is used to reduce a second electron transporter, the FAD</u>. For each turn of the cycle, a molecule of FADH2 is formed from FAD. O2 is not required for the Krebs cycle: <u>electrons and protons removed in carbon oxidation are accepted by NAD + and FAD</u>. It takes two turns of the cycle to complete the oxidation of a glucose molecule. Thus, the total energy efficiency of the <u>Krebs cycle for one glucose molecule is two molecules of ATP, six molecules of NADH and two molecules of FADH2.

Answer:
nonsense codon; shift in reading frame; nonsynonymous codon.
Explanation:
The mutation that affects the single nucleotide of nucleic acid are called as point mutation. It includes substitution, insertion or deletion of single base pair.
- When a premature nonsense or stop codon is inserted in the DNA sequence nonsense mutation occurs such as UAU is replaced by UAA (stop codon).
- A single nucleotide is added or deleted (shift in reading frame) in frame shift mutation.
- The amino acid are changed because of change in codon (nonsynonymous codon) by missense mutation.
- The mutation does not change the codon thus does not change the amino acid (synonymous codon) and does not express it are called as silent mutation.
