<span>The correct answer is b: Coenzyme A.</span>
During the process of pyruvate oxidation, acetyl CoA molecule is produced. Pyruvate oxidation is the link between glycolysis and Krebs cycle and it converts pyruvate (three-carbon molecule) into acetyl-CoA ( two-carbon molecule attached to Coenzyme A). NADH is produced and one CO2 released. AcetylCoA is the substrate for the next stage of cellular respiration, citric acid cycle.
Explanation:
The oldest fossil evidence of seed plants is of Late Devonian age, and they appear to have evolved out of an earlier group known as the progymnosperms. These early seed plants ranged from trees to small, rambling shrubs; like most early progymnosperms, they were woody plants with fern-like foliage.
Solution :
1. They can be reproduced on a human timescale --- renewable resources
2. They take millions of years to form -- non renewable resources
3. They are produced naturally -- renewable resources
4. They are extracted by mining -- non renewable resources
5. Their use as an energy source is increasing because they reduce pollution -- renewable resources.
<span>Sensations of somatic distress in waves lasting from 20 minutes to an hour at a time, a feeling of tightness in the throat, choking with shortness of breath, need for sighing, an empty feeling in the abdomen, lack of muscular power.
