Answer:
E. two of the above are correct
Explanation:
Fermentation reactions are processes that occur without the presence of oxygen and promote the release of energy (ATP) anaerobically. For these reactions to occur, glycolysis and reduction of pyruvate must occur.
These reactions allow the regeneration of NAD + that is necessary for the breakdown of glucose during the process called glycolysis, which is primarily responsible for the production of ATP. NAD + is regenerated from NADH.
With that, we can conclude that the correct options are:
B. often require the reactions of glycolysis to provide energy as ATP
C. supply NAD for the oxidation of glucose
We have seasons because the earth is tilted as it makes its way around the sun. So its always pointed in one way at the sun, causing different asmophere as we go around the sun.
Tight junctions are cell junctions that seal tissues. These junctions form protective and functional barriers.
- The cell junction that is involved in creating a barrier between cells is the TIGHT junction.
- The tight junctions are cell-cell adhesion structures implicated in cell polarity and signaling.
- On the other hand, adherens junctions are cell junctions required for maintaining contact inhibition.
- Finally, desmosomes are intercellular junctions that bind intermediate filaments of the cytoskeleton with cadherin proteins.
