In which situation would it be least likely for a scientist to revise her experimental methods

myrzilka [38]

Answer:

A, C, D

Explanation:

It is easier to look for which is wrong rather than checking all if they are right.

B is wrong because population A is growing exponentially and it can be inferred from the graph that it is nowhere near slowing down.

Example 1: Two different enzymes are able to catalyze the same reaction, A → B. They both have the same Vmax, but differ their K

luda_lava [24]

Answer: (a) = 0.022mmoles/minute; (b) = 0.00022mmoles/minute; (c) = 0.022mmoles/minute

Explanation:

The Michaelis- Menten equation is used to show the relationship between substrate concentration and reaction rate.

The equation is Vo = Vmax[S]/(Km + [S]

where Vo is the initial velocity, Vmax is the maximum velocity, [S] is the substrate concentration, Km is the Michaelis constant.

(a) For enzyme 1; Vo = 0.002mmoles/minute, Vmax = ?, [S] = 0.1mM, Km =1.0mM; making Vmax subject of the formula;

Vmax = Vo * (Km + [S])/ [S]

Vmax = 0.002*(1.0 + 0.1)/ 0.1

Vmax = 0.022mmoles/minute (Vmax for Enzyme 1&2)

(b) Vo = Vmax[S]/(Km + [S]

Vo = 0.022 * 0.1/(10+0.1) = 0.00022mmoles/minute

(c) Vo = Vmax[S]/(Km + [S]

Vo = 0.022*1000/(1.0+1000) = 0.022mmoles/minute

GLUT4 transporters are

Nuetrik [128]

Answer:

The correct answer is option a.

Explanation:

The GLUT-4 or glucose transporter type 4 refers to a protein encoded in humans. It is the insulin-regulated glucose transporter, which is found mainly in the striated muscles and adipose tissues. The increased level of insulin leads to the uptake of glucose into the cells. When insulin combines with the membrane receptors the GLUT-4, which is stored in the cell in the form of transport vesicles gets quickly assimilated into the plasma membrane. When the concentration of insulin becomes low, the majority of GLUT-4 gets sequestered in the intracellular vesicles in the fat and muscle cells.

Synapse plasticity

The ability of a given synapse to strengthen or weaken over time is known as synapse plasticity. The strengthening or weakening is in direct relation to the amount and way the synapse is used. The more frequently and vigorously a synapse is involved in activities, the more it will strengthen, just as in the case of muscles. This mechanism is important in learning and also lays the foundation of memory in the brain.
