Identify how many carbons from one glucose molecule enter one round of the Krebs cycle

1 answer:

5 0

The answer is, all three carbons from glucose molecules enters the Kreb cycle. But three at a time only. One molecule is broken down to two pyruvate molecules and then used in Krebs cycle. Which means that one glucose molecules leads to two cycles of the Kreb cycle with three carbons going to the cycle at one time.

Which of the cell junctions is involved in creating a barrier between cells?

aleksklad [387]

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.

Apply what you know about lipids to explain why the cuticle helps prevent water loss in plants. Compare it to what humans do.

yulyashka [42]

Explanation:

Waxy cuticle is a white powdery substance that is insoluble, it is found usually on the surface of stem or leave and it prevent excessive loss of water through transpiration.

It is an adaptive mechanism used in dry areas or desert to help plants retain water that is needed for their growth by reducing amount of water loss through transpiration.

Fossil seashells have been found in rock beds on land. what can you infer about how the area has changed

olga55 [171]

When we go to the beach one of the most exiting activities that we do is of course collect the best looking seashells. Now I have never seen seashells in another place other than the beach.

My point in this entery that I have just mentioned is that where there is seeashells there is body of water. What those fossils mean is that that particular place whhere those seashells were once found means that maybe a very long whille back that place was onetime a body of water. Some natural dissaster came and that place doughtet and the water moved to some place else.

My pleasure to help, over and out ;)
