Cystathioninuria can be caused by two different mutations in the enzyme cystathionase. Cystathioninuria caused by mutation 1 can
polet [3.4K]

Answer:

C. The enzyme with mutation 1 has decreased affinity for pyridoxal phosphate, whereas the enzyme with mutation 2 has lost the ability to bind to the substrates.

Explanation:

A coenzyme is an organic cofactor that binds with an enzyme in order to initiate or aid the function of the enzyme. A coenzyme binds to the active site of the enzyme (where the reaction occurs), thereby triggering its activation by modifying protein structure during the reaction. Some examples of coenzymes include Coenzyme A and Adenosine triphosphate (ATP). Pyridoxal phosphate is a coenzyme (it is the active form of vitamin B6) that is required for the function of cystathionase. Moreover, cystathionase is an enzyme that enables cells the synthesis of cysteine from methionine (transsulfuration pathway). The binding of pyridoxal phosphate to the enzyme increases the binding affinity of the enzyme for the substrate, thereby influencing its activity. In this case, it is expected that mutation 1 reduces the binding affinity of the enzyme to the cofactor, and thereby the cofactor is required at a higher concentration to restore normal enzyme activity.

What is the major function of a leaf
ANEK [815]

Answer:

Photosynthesis

Explanation:

The leaf (from Latin fŏlĭum, fŏlĭi) is the vegetative and generally flattened organ of vascular plants, specialized mainly to perform photosynthesis. The morphology and anatomy of stems and leaves are closely related and, together, both organs constitute the stem of the plant.

Typical leaves - also called nomophiles - are not the only ones that develop during the life cycle of a plant. From the germination, different types of leaves follow each other - coiled, primordial leaves, prophilic, bracts and antophiles in flowers - with very different forms and functions.

A nomophile usually consists of a flattened sheet, a short stem - the petiole - that joins the sheet to the stem and, at its base, a pair of appendages - the stipules. The presence or absence of these elements and the extreme diversity of forms of each of them has generated a rich vocabulary to categorize the multiplicity of types of leaves presented by vascular plants, whose description is called foliar morphology.
