An enzyme possesses different kinetics for different substrates as a result of this different products are formed.

Discussion:

Multi-substrate reactions are governed by intricate rate equations that specify how and in what order the substrates bind. If substrate B is altered while the amount of substrate A remains constant, the study of these reactions becomes considerably easier. The enzyme behaves exactly like a single-substrate enzyme in these circumstances, and a plot of v by [S] yields the actual KM and Vmax constants for substrate B.
These results can be utilized to determine the reaction's mechanism if a series of such measurements are carried out at various fixed concentrations of A. There are two different sorts of mechanisms for an enzyme that accepts two substrates, A and B, and converts them into two products, P and Q: ternary complex and ping-pong.

Cells a and b are the same size and shape, but cell a is metabolically quiet and cell b is actively consuming oxygen. Oxygen wil

Juli2301 [7.4K]

The two cells of the similar shape, and size have different levels of the ongoing metabolic activity. On one hand, the cell a is metabolically quiet, which means that no energy consuming chemical reactions are taking place in this cell. On the other hand, the cell b is actively consuming the surrounding oxygen. In this scenario, the oxygen will more quickly diffuse into the cell b because the diffusion gradient for oxygen in this cell is steeper than in the cell a.

Hence, the blanks can be filled with 'b and the diffusion gradient is steeper' respectively.

A daughter cell that matures to the inside of the vascular cambium becomes ______, and a daughter cell that matures to the outsi

melomori [17]

A daughter cell that matures to the inside of the vascular cambium becomes secondary xylem and a daughter cell that matures to the outside of the vascular cambium becomes secondary phloem.

The cambium divides its cells to create secondary xylem and phloem. As secondary phloem and xylem tissue builds up, the stem becomes thicker and develops wood and bark.

The kind of xylem produced by secondary growth is known as secondary xylem. In contrast, during primary growth, the primary xylem develops.
As a result, lateral growth, as opposed to vertical growth, is connected with the secondary xylem, as opposed to the primary xylem.
The procambium, which is found between the xylem axis and the phloem pole, develops into the cambium in the root.
A pattern resembling the arrangement of secondary stem is produced when xylem forms in the core and phloem on the perimeter of secondary development.

A patient has taken levodopa [Dopar] for Parkinson's disease for 2 weeks but reports no improvement in the symptoms. Which respo

Elan Coil [88]

Answer:

Option-D

Explanation:

Parkinson's diseases are a neural disorder which affects the movement of the human body. The disease is caused by the low production or no production of dopamine by the neurons which thus interfere with the impulse transfer and thus movement.

In the given question, the patient with Parkinson's disease is provided with levodopa but no improvement is observed therefore the prescriber must change the drug regimen, for example, the levodopa should be given in combination with carbidopa. These medications enter the blood-brain barrier and get converted to the dopamine.

Thus, Option-D is the correct answer.
