How does the semipermeable membrane work?

When glucose is taken into the cell, the fluids or solutions in the cell become more concentrated (due to the absorbed glucose) than the fluids outside the cell. When this happens, a natural process called osmosis takes place .

Osmosis is defined as the movement of molecules of a solvent (in this case water) through a semi-permeable membrane (in this case the cell membrane) from a less concentrated solution to a more concentrated one in a bid to to equalize the concentration on both sides of the membrane.

<span>Water will therefore leave the less concentrated solution outside the cell, pass through the cell membrane and into the more concentrated solution.</span>

Explain why serine proteases do not catalyze hydrolysis if the amino acid at the hydrolysis site is a D-amino acid. Trypsin, for

kotykmax [81]

Answer:

Explanation:

A protease is an enzyme that catalyzes the hydrolysis of the peptide bonds that tie polypeptide chains together, releasing individual amino acid subunits. The L and D nomenclature for amino acids defines the structure of the glyceraldehyde isomer through which the amino acid can be produced.

SEE BELOW FOR THE APPROPRIATE STRUCTURES.

We need to figure out why swine proteases hydrolyze L-amino acids but not D-amino acids in any way. we know that enzymatic catalysts act as polypeptides if you can recall. They must retain a very precise three-dimensional structure for a catalytic activity to occur. Substrates that do not quite match the required configuration at the active site will not be reacted to — this is a "lock and key" style.

The present exercise may be explained by the fact that the configuration and structure of D-amino acids prevent them from binding properly to the active site of the protease enzyme. Perhaps they're pointed in the wrong direction, or perhaps there happens to be missing electrical interaction that's needed to keep the substrate in position.

Nonetheless, L-amino acids, on the other hand, seem to have the right configurational aspects in the active site and are hydrolyzed.

Compare the processes by which a car and a human use "fuel" to perform work. What are the similarities?

Alenkinab [10]

A car needs to be fueled before it can set in motion to posses a given amount of kinetic energy.

<h3>What is energy?</h3>

Energy is the capacity of doing work. In physics, there exist different types of energy; among which are follows:

Kinetic energy: Kinetic energy can simply be defined as that energy a body posses due to its motion
Potential energy: , On the other hand, potential energy is the energy a body has due to its relative position.

Other forms of energy include:
