When Does The Transport Rate Reach Maximum In Facilitated Diffusion?

In facilitated diffusion, the transport rate reaches a maximum when all the protein transporters are used up (Saturation).

No, facilitated diffusion cannot cause total transportation of molecules from a lower to a higher concentration.

Substances having a hydrophilic moiety, find it difficult to pass through the membrane. Hence, their movement has to be facilitated.

Substances soluble in lipids diffuse faster through the membrane.

Yes, the diffusion of any particle across a membrane is dependent on the solubility in lipids.

The diffusion rate depends on the size of substances, smaller substances have a faster rate of diffusion.

In diffusion, molecules move randomly.

Diffusion rates are affected by the permeability of the membrane separating them, concentration gradient, pressure and temperature.

Yes, the rate of diffusion is affected by the gradient of concentration.

Diffusion is a slow process and is not dependent on a ‘living system’.

It refers to the number of sets of chromosomes in the genome of a cell.

When two gametes fuse in sexual reproduction, the chromosome number gets restored to the value in the parent.

Chromosome condensation occurs during prophase.

The G2 phase is the period of cytoplasmic growth.

Meiosis ends with telophase II.

Microtubules at metaphase II from the opposite poles of the spindle get attached to the kinetochores of the sister chromatids.

The chromosomes at metaphase II, align at the equator.

Towards the end of prophase II, the nuclear membrane disappears.

Interkinesis is followed by prophase II. This prophase is simpler compared to prophase I.

During interkinesis, there is no replication of DNA.
