These are all correct! Hope this helps :)
aeorbic respiration occurs in the mitochondria
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.
<span>Her intestinal contents became hypertonic solution to her blood. Her blood became hypotonic solution to her intestinal contents. In hypertonic solution the total substance concentration of all dissolved solute is greater than the concentration in a cell. In hypotonic solution the substance concentration of all dissolved solute is less than that of a cell.</span>
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.
