The 3 is vaporization and solidification
4 is vaporization
5 is solidification
Answer: Diatoms.
Explanation:
Diatoms are single celled group of algae that are found in aquatic habitat both freshwater and marine habitat. The are the most important primary produce in the marine habitat. They are photosynthetic I .e they have chlorophyll which help them to trap light energy from sunlight and uses carbon dioxide and water to produce food. They produce food with the process of photosynthesis.
Fixation during which the enzyme RuBisCO incorporates (fixes) carbon-dioxide into 3-PGA; 2. Reduction during which 3-PGA is reduced using NADPH as electron supply; 3. Regeneration during which RuBP<span> is regenerated so the cycle can start again.</span>
<span>You are likely talking about aerobic respiration rather then just glycolysis based on the options: The third option seems best, pyruvate is heavily oxidized during the Kreb's cycle and removed as CO2.
Wrong options
Option1- FADH2 is also another highly energetic molecule produced during
Option2- oxidation of pyruvate is a highly directional process and can be considered irreversible in the cell
Option4- Aerobic respiration RELEASES energy from pyruvate and the into NADH/FADH which is then captured by the electron transport chain. An exergonic rxn would take in energy and would not happen spontaneously
This can be looked from different perspectives, but let me know if my answer made sense. </span>
