What did the large prokaryotic cell provide the mitochondria and/or chloroplast ancestors?

1 answer:

3 0

Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. At some point, a eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion.

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

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

How does contracting the vacuole affect the volume of the paramecium? AHhhhh pls help

Where in the integumentary system are blood vessels found, and how do these vessels react when the body is cold? epidermis; the

Rama09 [41]

In Integumentary system blood vessels are found in dermis and the blood vessels contract when the body is cold.
Dermis and epidermis are layers of the skin, dermis is the thick layer of tissues and it is present under the epidermis layer.
When we feel cold, our body supplies the warm blood to the skin. When contraction of blood vessels occurs, it reduces the flow of warm blood and reduces the heat loss. When we feel hot, blood vessels dilate.

Answer:I think it was The Heat waves can be dangerous, causing illnesses such as heat cramps and heat stroke, or even death. Warmer temperatures can also lead to a chain reaction of other changes around the world. That's because increasing air temperature also affects the oceans, weather patterns, snow and ice, and plants and animals
