Substances that plug up an enzyme active site and prevent the reaction from occurring are enzyme inhibitor

Enzyme inhibitors are molecules that temporarily or permanently interact with enzymes in some way, reducing the rate of an enzyme-catalyzed reaction or preventing enzymes from functioning normally. Competitive, noncompetitive, and uncompetitive inhibitors are the three main categories of inhibitors.

Enzyme inhibitors are substances that alter the enzyme's catalytic capabilities. As a result, they reduce the enzyme's ability to catalyze reactions or, in extreme cases, completely stop them. These enzyme inhibitors function by obstructing or changing the active site.

It is possible to define enzyme inhibitors as substances that attach to enzymes and reduce their activity. They attach to the enzymes' active sites and reduce the enzymes' compatibility with substrates, which prevents the formation of enzyme-substrate complexes.

Which two phenomena are evidence that gravitational forces are attractive? Select two statements.
Vinvika [58]

Answer:

A. the rise and fall of the tides.

C. a dropped object always falls toward Earth.

Explanation:

Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.

Additionally, the gravity of earth makes it possible for all physical objects to possess weight.

The two phenomena which are evidence that gravitational forces are attractive includes;

I. The rise and fall of the tides: this is caused as a result of the gravitational force of attraction exerted by the moon on earth.

II. A dropped object always falls toward Earth: this acceleration is due to the gravitational force of attraction between the Earth and the object.

Predict phenotypes associated with nondisjunction of sex chromosomes.
Mnenie [13.5K]

Answer: The new daughter cells will have an abnormal amount of genetic material. That is called aneuploidy and it is the presence of an abnormal number of chromosomes. Different clinical conditions are the result of this nondisjunction.

Explanation:

Normal cells are diploids, that means they have two copies of each gene, one of each chromosome. So normal cells have two homologous chromosomes, one from each parent.

During anaphase of cell division, each pair of chromosomes is separated  by the mitotic spindle. The separated chromosomes are then pulled by the spindle to opposite poles of the cell, and eventually will end up in the new daughter cells.

Nondisjunction is the failure of homologous chromosomes to separate properly during cell division, so it is the miss segregation of them. The new daughter cells will have an abnormal amount of genetic material. <u>Different clinical conditions are the result of this nondisjunction.</u>

Sex chromosomes participates in sex determination of an individual. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY) So nondisjunction of sex chromosomes could be:

  • XX: one cell with no chromosome and the other cell with two X chromosomes.
  • XY: one cell with no chromosomes and the other cell with XY chromosomes.

According to which gametes are fused during fertilization, different phenotypes can be given. For example, if a gamete with one chromosome fuses with another gamete with two chromosomes, the result will be an individual with three chromosomes (it could be XXY, or XXX) called trisomy.

Triple X syndrome is characterized by an extra X chromosome in females. Those affected are often taller than average, but most females have a normal sexual development. Klinefelter syndrome is known XXY individuals, and it causes infertility in males, breast growth, less body hair and weaker muscles.

And if a gamete with no chromosome fuses also with another gamete with no chromosome, the result is a nullisomy. But due to the lack of genetic material, the nullisomic gametes are rendered unviable for fertilization.

And if a gamete with no chromosome fuses with another gamete with one chromosome (normal) the result is a monosomy, the presence of only one chromosome from a pair. The result can be an individual who is X or Y. People with Turner syndrome have one X chromosome and it is the only monosomy that is seen in humans because other cases monosomy are lethal.

Any of those examples is called aneuploidy and it is the presence of an abnormal number of chromosomes.
