Lactose tolerance and intolerance together with other northern European individuals Lactose, the sugar found in dairy items and drain, is processed by the catalyst lactase.
Lactose intolerance is a typical stomach related issue where the body can't process lactose, a sort of sugar mostly found in drain and dairy items. Manifestations of lactose intolerance, as a rule, create a couple of hours of devouring nourishment or drink that contains lactose.

Answer:

D. Allosteric activator

Explanation:

In an enzyme, the allosteric site is a site/motif different from the active site, (i.e., the site with catalytic activity) which is able to interact with regulatory effector molecules in order to activate or inhibit enzymatic activity by influencing the tridimensional (3D) structure of the enzyme. An allosteric activator is an effector molecule with the ability to bind to a specific enzyme at a different site than the active site, thereby modifying the shape of the enzyme and increasing the affinity of this enzyme for its substrate. Moreover, Adenosine monophosphate (AMP) is a nucleotide composed of a phosphate group, a sugar ribose, and an Adenine (A) base. This effector molecule (AMP) has shown to allosterically stimulate diverse enzymes in physiological conditions (e.g., AMP-activated protein kinase).

If you lined up human skin cells side-by-side, how many would fit along the length of the paperclip in the sample problem above?

dimaraw [331]

Hi,

You did not provide the length of paper clip but i searched this exercise to find the length of the paper clip as So, a small paperclip measures 3.0 cm so i will answer your question according to this length.

The size of a human cell is around 30um and the question is asking that how many would fit along the length of the paper clip measuring 3cm.

3 cm = 30000 microns

= 30000/30

= 1000 cells.

So, if we line up 1000 human skins cells side-by-side, they would fit along the length of the paperclip.

Note: <em>If the length of paper clip is different in your excercise like 1 cm etc, simply multiply the 1 with 10000 and divide the resultant value with 30, this way you can get cell number for the length of any clip.</em>

Hope it helps!
