NADH is also used by cells when making certain molecules. Based on your knowledge of the role of NADH in cellular respiration, w
chubhunter [2.5K]

Answer:

b. reducing molecules

Explanation:

Nicotinamide adenine dinucleotide (abbreviated NAD +, and also called diphosphopyridine nucleotide and Coenzyme I), is a coenzyme found in all living cells. The compound is a dinucleotide, as it consists of two nucleotides linked through their phosphate groups with a nucleotide that contains an adenosine ring and the other that contains nicotinamide.

In metabolism, NAD + participates in redox reactions (oxidoreduction), carrying electrons from one reaction to another.

Coenzyme, therefore, is found in two forms in cells: NAD + and NADH. NAD +, which is an oxidizing agent, accepts electrons from other molecules and becomes reduced, forming NADH, which can then be used as a reducing agent to donate electrons. These electron transfer reactions are the main function of NAD +. However, it is also used in other cellular processes, especially as a substrate for enzymes that add or remove chemical groups of proteins, in post-translational modifications. Due to the importance of these functions, the enzymes involved in the metabolism of NAD + are targets for drug discovery.

Archaebacteria look much alike organisms from what other kingdom due to their similar shapes?
Goshia [24]

Step-by- step-Explanation:

  • Archaebacteria are very similar to Bacteria with respect to their cell size,prokaryotic organisation,circular DNA etc.
  • Archaebacteria very similar to Gram-positive bacteria on the basis of cell structure.
  • Both bacteria and Archaebacteria have several similar Metabolic Pathways.
  • Unlike Bacteria Archaebacteria are habitants of extreme climates like hot springs and ice capped continents.

Thus Archaebacteria are much alike to Eubacteria.
