Marine iguanas are the only sea going lizard on the planet? True False

dimaraw [331]

True. Marine iguanas are the only lizard that can survive in the sea. They live, mate and nest on land, but the sea is their feeding ground. They have a special gland near their nostrils that removes excess salt in their bodies from eating sea algae.

Enzyme X has a primary structure made up of 130 amino acids. In tertiary structure amino acids numbers 56, 58, 81-84, and 91-95

Fantom [35]

Question:

The question is unclear but I think I found it elsewhere and have rewritten it below:

Enzyme X has a primary structure made up of 130 amino acids. In tertiary structure amino acids numbers 56, 58, 81-84, and 91-95 form the active site.

Looking at the data in the attached table, determine the category of unknown molecules A, B and C.

1) A = cofactor B = non-competitive inhibitor C= non-competitive inhibitor

2) A = competitive inhibitor B = not a cofactor C= non-competitive inhibitor

3) A = not a cofactor B = competitive inhibitor C= non-competitive inhibitor

4) A = non-competitive inhibitor B = non-competitive inhibitor C= competitive inhibitor

5) A = competitive inhibitor B = non-competitive inhibitor C= non-competitive inhibitor

Answer:

2) A = competitive inhibitor B = not a cofactor C= non-competitive inhibitor

Explanation:

A competitive inhibitor is a molecule that binds to the active site of an enzyme, directly blocking its ability to catalyse reactions and thus inhibiting its activity. A non-competitive inhibitor inhibits the activity of an enzyme, but not through binding an active site. A co-factor is an accessory protein that influences and promotes the activity of the enzyme

The table shows that unknown molecule A binds to the active site (based on the amino acid positions at which it binds) and reduces the activity of the enzyme (from 31.8 - 11.4) - a competitive inhibitor

Unknown molecule B does not bind at the active site, and has no affect on the activity of the enzyme - not a co-factor or an inhibitor

Unknown molecule C does not bind to the active site, but strongly reduces the activity of the enzyme - a non-competitive inhibitor

What are the gametes that would be formed for the following genotype: Aa?

dlinn [17]

Answer:

A and a

Explanation:

GAMETE formation occurs via a process called MEIOSIS. During meiosis, segregation and independent assortment of genes occur. According to Gregor Mendel who proposed the law, the law of segregation states that the alleles of a Gene will separate into gametes. This separation occurs in such a way that only one allele of that gene is found in each gamete.

In this case, an organism with genotype "Aa" will produce gametes that contains the following: A and a. Therefore, the gametes of genotype Aa will be A and a.
