If an enzyme inhibitor binds at a site other than the active site of the enzyme, the nature of the inhibitor is described as
icang [17]

Answer:

B. non-competitive

Explanation:

As opposed as competitive inhibition, the non-competitive one does not bind with the active region of the enzyme. However, it does reduce the efficiency of the reaction because it changes the protein structure, making it unavailable for substrate.

Reversibility is related to the possibility of the reaction to be undone. If the bond is covalent, the enzyme will not return to its active state, so that would be a non-reversible bind.

A) Describe the first interaction that triggers signaling to begin in a target cell.
sergey [27]

Answer:

Ligand-receptor interaction is the first interaction that triggers cell signalling.

Ligands are the hormones, drugs or neurotransmitters that specifically bind with receptors present in cell surface to initiate cell signalling. Ligand binding to the receptor is reversible. Binding of the ligand to the receptor can activate or inactivate receptor. Activation may lead to cell signalling pathways. Inside cells, there are secondary molecules which on activation starts a cascade of reactions. which in-turn regulate the function of the ligand molecule.

At first, the activated receptor relates with G proteins molecules in the cell.

before the ultimate physiological effect of the ligand on the cell's behavior is produced Therefore, the cellular signaling starts as soon as the first messenger (the ligand) binds to its receptor.

hope this helps

In a population of 286 individuals express the recessive be a GNODYPE what scent of the population would you predict would be he
Cerrena [4.2K]

Procreation comes from pairing. In different phrases you have 2 codes for each little thing. you have the code from the father and the code from the mother. evaluate the code for blood. you're attentive to that there are 4 varieties of blood variety O, variety A and variety B and variety AB. If mom has 2 codes for her blood, enable us to declare O and O and father has 2 codes for his blood enable us to declare O and A There are a sequence variety of combinatins the 1st mom O can combine with father O, OO The 2d mom O can combine with father A, OA. the 1st mom O can combine with father A, OA The 2d mom O can combine with father O, OO the baby is going to have the two OO or OA. If the baby has OO the the baby has no selection different than to have blood variety O because of fact the expressed phenotype. If the baby has OA the A is dominate and it takes expression. subsequently the only way a recessive allele could be expressed is that if and on condition that there are 2 recessive allele as interior the case of OO. Now do the different combinations mom OO mom OA mom AA mom OB mom BB mom OO can combine with father OO making OO mom OO can combine with father OA making OA mom OO can combine with father AA making OA mom OO can combine with father OB making OB mom OO can combine with father BB making BB The recessive allele is expressed if and on condition that the two codes are recessive. What if mom is dominant A. mom AA mom OA can a recessive allele be produced particular If and on condition that the recessive O of the mother combines with a recessive O of the father. subsequently a mom dominant A might desire to be coded as OA and a father dominant A might desire to be coded as OA. the baby can get carry of mom O blended with the father O and be OO, the recessive. the baby is recessive even whilst the mothers and dads are dominant because of fact the mothers and dads carried the recessive allele. this might ensue if and on condition that the two mothers and dads carry the recessive allele. pass via the mixture mom OA Father AA you will by no capacity get a recessive phenotype expressed

A forest is cut down to plant a field of corn. How will this affect the biodiversity of the area?
zzz [600]
It would affect our environment very badly. The following reasons are why it is bad: 1)Trees are our main supply of oxygen. 2) Corn is slow at converting carbon dioxide into oxygen. 3) Many wildlife creatures (plants and animals) need that ecosystem to live.
