The part of the eye that prevent light from reflecting internally and is heavily vascularized to deliver blood to the retina:___
Ne4ueva [31]

The part of the eye that prevent light from reflecting internally and is heavily vascularized to deliver blood to the retina: choroid.

<h3>What is choroid?</h3>

The choroid is highly vascularized to provide blood to the retina and contains dark pigmentation to stop light from reflecting inside. Anteriorly, the choroid, ciliary body, and iris are all joined.. The ciliary body muscles regulate the lens's thickness. The iris acts as a diaphragm, changing the pupil's aperture at its center. This regulates how much light is allowed to enter the retina. In strong light, the iris' muscle fibers constrict the pupil to accommodate close vision; in low light, they enlarge it to accommodate far vision. Each individual's iris is a different color.

Aminolevulinate dehydratase (ALAD ) is an enzyme that relies on zinc as a coenzyme. A zinc ion binds to the ALAD active site, wh
slavikrds [6]

Answer:

The correct option is C. It changes the three-dimensional structure of the active site so that ALAD is no longer compatible with its substrate.

Explanation:

Co-factors are molecules that are required by an enzyme to perform its function of catalysis. If a wrong co-factor binds to the enzyme then it will change the three-dimensional structure of the enzyme and the substrate will no longer fit into the enzyme. Hence, Option C is the best choice that explains the inhibition of ALAD.

Other options are false because :

Option A: The wrong co factor will not affect the substrate nor will it make it compatible for ALAD's active site.

Option B:  The wrong factor doesn't change the amino acid sequence of the protein or enzyme, rather it changes the three dimensional structure of the enzyme.

Option D : The wrong co factor won't allow the reaction to proceed at a faster rate, rather it will inhibit the reaction.
