In endoplasmic reticulum, many folds leads to an increase in surface area for ribosomes to attach which allows for protein synthesis to occur at an efficient rate.

mitochondria has two membrane,

It has an inner membrane which is folded inside the other. The fold create cristae, which is the site for a portion of cellular respiration.

The folds also enables a large surface area that makes chemical process to occur in an efficient way.

erica [24]

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).

The order primate holds 300 or more species including monkeys, humans, gorillas, chimpanzees among others. The species included in this order share anatomic and functional characteristics such as:

  • Hands and feet with 5 fingers and opposable thumbs, for grabbing, holding a grip for a better arboreal lifestyle. Even though in some species such as humans these opposable thumbs in feet don't longer exist.
  • Plantigrade feet, which means that the toes and metatarsals are flat on the ground while walking.
  • Collarbone or clavicle present.
  • Nails instead of claws in the large majority of species.
  • Color vision.
  • Two brain hemispheres well developed, for special traits like social behaviors and better eye-hand coordination among others.
