Answer:  The shape of an enzyme determines which reaction it can catalyze.

Explanation: The shape of an enzyme is very important because it has a direct effect on how it catalyzes a reaction. An enzyme's shape is determind by the sequence of amino acids in its structure, and bonds which then form between the atoms of those molecules. There are steps of the catalytic cyle of an enzyme and are as follows:

1. The enzyme has an empty active site and is available.

2. The substrate binds to the enzyme with induced fit.

3. The substrate is change to the products.

4. Finally the enzyme releases the products.

Hope this helps.

What do you get when you cross a fast dog with a bumblebee?
Dahasolnce [82]

I'm afraid that is not possible since those two are very distant animals genetically since they're not part of the same species, genus nor family.

But if it was possible, you could either obtain a dog with bublebee traits or a bumblebee with dog traits for example.


Hope it helped,

Which statement best describes the events responsible for the phase represented by the letter B in the figure?
Gemiola [76]

Answer:

opening of sodium channels

Explanation:

Sodium channels are integral membrane proteins that form ion channels, conducting sodium ions (Na+) through a cell's plasma membrane. Sodium channels are the founding members of ion channel super-family that includes voltage-gated calcium channels, TRP channels, voltage-gated, inward rectifying, and two-pore-domain potassium channels, and cyclic nucleotide-regulated CNG and HCN channels. When the neuron becomes stimulated the voltage gated sodium channels begin to open and the membrane potential begins to slowly depolarizes and sodium enters the cell down its concentration gradient.

A particular cell has a mutation that causes it to make defective centromeres. What would you expect to occur during mitosis for
cluponka [151]

Answer:

Chromosomes will not align at the equator of the cell, and subsequently will not separate to opposite poles.

Explanation:

Mitosis is a cellular division that results in daughter cells with identical copies of the genetic material as the parent cell. Mitosis is characterized by different stages viz: Prophase, Metaphase, Anaphase, and Telophase. The centromere is a very important part of the cell during division as it produces microtubules that grows out and bind to the kinetochore of each chromosome, hence, aligning them at the CELL PLATE (cell equator) and subsequently pulls them apart to opposite poles. This alignment and pulling apart occurs during METAPHASE and ANAPHASE respectively.

Mutation is any change that occurs in the nuceleotide sequence of the genetic material (DNA). If a change/mutation occurs leading to a defective or non-functional centromere, the centromere will no longer be able to produce microtubules that will bind to the kinetochores of each chromosome. Therefore, the chromosomes will be unable to align at the equator/middle of the cell and most importantly, inability to separate to opposite poles, which is the main point of Mitosis.
