Which statement is FALSE about allosteric regulation?

Cellular response is faster with allosteric control than by controlling enzyme concentration in the cell.
The regulation usually is important to the conservation of energy and materials in cells.
Allosteric modulators bind non-covalently at sites other than the active site and induce conformational changes in the enzyme.
It is usually the mode of regulation for the last step in reaction pathways since this step produces the final product.

It is usually the mode of regulation for the last step in reaction pathways since this step produces the final product.

Explanation:

Some enzyme are allosterically regulated in which an effector molecule regulate the activity of enzyme by binding to it other than the active site. That site is known as allosteric site. These effector molecules change the conformation, shape and functions of enzyme and may be either allosteric activators (enhance enzyme activity) or allosteric inhibitors (decrease protein activity).

Coopertivity is the process in which substrate itself act as allosteric activator and increase the activity of enzyme by binding to one active site.

Cellular response is faster with allosteric control than by controlling enzyme concentration in the cell because controlling the enzyme concentration would involve the Central Dogma process, which would take time.

Allosteric regulation is not specified to last step of reaction because it decrease or increase the speed of reaction. The last step depends on initial steps.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
