Answer: irreversibly binds and inactivates the enzyme.
Explanation: An enzyme can be defined as any substance that binds substrates in a manner that facilitates the formation of product.
These are nonspecific factors that would inactivate any enzyme. The activity of enzymes can also be regulated by more specific inhibitors. A competitive inhibitor can be defined as an inhibitors bind reversibly at the active site of an enzyme.
It is important to note the difference:
An irreversible inhibitor inactivates an enzyme by bonding covalently to a particular group at the active site. The inhibitor-enzyme bond is so strong that the inhibition cannot be reversed by the addition of excess substrate.
A reversible inhibitor inactivates an enzyme through noncovalent, more easily reversed, interactions. Unlike an irreversible inhibitor, a reversible inhibitor can dissociate from the enzyme. Reversible inhibitors include competitive inhibitors and noncompetitive inhibitors.
Answer:
There are 4 different fundamental states of matter: solid, liquid, gas, and plasma.
The atoms/molecules that make up a solid are packed <u>tightly</u> together and arranged in regular, repeating patterns. They are held firmly in place by their attractive forces and their <u>low kinetic energies</u> but do vibrate within a limited area. Solids, have a <u>fixed</u> shape and volume.
In liquids, the atoms/molecules have a moderate kinetic energy and flow easily around one another. They are kept from flying apart by attractive forces between them. Liquids have a fixed <u>volume</u> but assume the <u>shape</u> of their containers.
Atoms/molecules in gases fly in all directions at great speeds. Due to this <u>high</u> kinetic energy, attractive forces between them are <u>insignificant</u>. Gases assume the volume and shape of their containers.
Lastly, plasma is the state of matter with the highest thermal energy. It is made up of free electrons and the positive ions from which they came. The electrons freely move around within this system of positive ions in a similar way to <u>gases</u> . Plasmas are strongly influenced by electric and magnetic fields due to the charged particles.
Answer:D. astrocytes
Explanation:
glial cell are any of several types of cell that function primarily to support neurons its divided into four groups namely oligodendrocytes,
astrocytes, microglia, and ependymal cells. The astrocytes plays a key role in regulating ions, uptake and/or breakdown of some neurotransmitters, and contribute to the formation of the blood-brain barrier.
Answer:
The lungs are the organs most affected by coronavirus
Los pulmones son los órganos más afectados por coronavirus
Explanation:
The correct answer or option is cerebrum
The cerebrum, also called cortex is the largest part of the brain.
It is divided into four sections, called lobes and these are the frontal lobe,
the parietal lobe, occipital lobe and temporal lobe.
Front lobe helps in speech, reasoning, planning, movement ,
emotions and problem solving.
parietal lobe helps in orientation, and perception of stimuli and
movement.
Occipital lobe helps in visual processing.
Temporal lobe helps in memory, speech as well as perception and
recognition of auditory stimuli
