Enzyme Inhibitors bind to an enzyme to turn it off, thus preventing it from catalyzing a reaction.
An enzyme is a biological molecule that catalyzes chemical reactions in the cell. Enzymes work by lowering the activation energy required for a reaction to occur, making it more likely that the reaction will proceed. However, enzymes can also be inhibited, which means that their activity is reduced or stopped completely. This can happen for a variety of reasons, such as the presence of a specific molecule called an inhibitor.
Some inhibitors bind to the active site of the enzyme, preventing the substrate from binding and thus preventing the reaction from occurring. Other inhibitors bind to other parts of the enzyme, causing a conformational change that prevents the enzyme from working. Still, other inhibitors bind to enzymes and alter their activity by non-covalent interactions.
There are different types of inhibitors like competitive inhibitors bind to the active site of an enzyme and prevent substrate binding. Non-competitive inhibitors bind to a different site on the enzyme, causing a conformational change that makes the enzyme less active. Feedback inhibitors bind to the end product of a metabolic pathway, inhibiting the enzyme that catalyzes the first step of the pathway.

Kinetic energy increases as mass increases
The shape of the mass vs energy graph shows a linear relationship
When we double the mass, we double the energy.
Interpreting a graphThe graph shown in the image is a plot of the kinetic energy of objects on the y-axis and the mass of the objects on the x-axis.
The graph is a straight line. This shows that there is a linear relationship between the two parameters - the kinetic energy and mass of objects. Thus, the kinetic energy increases as mass of objects increases, and decreases as mass of objects increases.
From the graph, when the mass of objects are doubled, there is also a double in the amount of the kinetic energy of objects.
In summary, the graph shows that:

Lead absorption is decreased by the presence of ______ in the body. a) calcium and vitamin D b) calcium and iron c) iron and selenium
Answer: Correct option is B . calcium and iron decrease the absorption of lead in the body.
Explanation: calcium and iron decrease the absorption of lead in the body without affecting its solubility,probably by competing for shared absorptive receptors in the intestinal mucosa. The total body burden of lead does not affect lead absorption. Thus, lead does not have a feedback mechanism which limits absorption.

Calcium phosphate, Ca 3(PO 4) 2, is used to treat calcium deficiencies. What is the molar mass of this compound
Ca3(PO4)2 has a molar mass of 310.18 g/mol.
Molar mass: What is it?The sum of the molar masses of a compound's component parts determines its molar mass. The molar masses of calcium, phosphorus, and oxygen must be added up in order to determine the molar mass of Ca3(PO4)2.
The molar mass of calcium is 40.08 g/mol.
The molar mass of phosphorus is 30.97 g/mol.
The molar mass of oxygen is 16.00 g/mol.
There are 3 moles of calcium, 2 moles of phosphorus, and 8 moles of oxygen in the compound Ca3(PO4)2.
As a result, the formula for calculating the compound's molar mass is: 340.08 + 230.97 + 8*16 = 120.24 + 61.94 + 128 = 310.18 g/mol
Consequently, Ca3(PO4)2 has a molar mass of 310.18 g/mol.

Which of the following is the strongest type of interaction that occurs between the atoms within the circled areas of the two molecules represented above? A) Polar covalent bond B) Nonpolar covalent bond C) Hydrogen bond D) London dispersion forces
The strongest type of interaction that occurs between the atoms is hydrogen bond.(option c)
A hydrogen atom that is bound to a highly electronegative atom and another highly electronegative atom that is close by interact with one another to form hydrogen bonds, which are an unique kind of attractive intermolecular interactions. This process is known as hydrogen bonding.
As a result of hydrogen bonding, a hydrogen atom simultaneously forms a covalent bond with one electronegative atom and a hydrogen bond with the other. These are the prerequisites for hydrogen bonding:
1.A strongly electronegative atom connected to the hydrogen atom must be present in the molecule. The degree of polarization of the molecule increases with increasing electronegativity.
2.The electronegative atom should have a tiny size. The strength of the electrostatic attraction increases with decreasing size.
So, the hydrogen bonding is the strongest bond.

Be as explicit as you can in describing how the covalent bond between an atom of Chlorine and an atom of Iodine forms. (What happens to the electrons, which electrons are involved, and what allows this to happen MUST all be part of your answer to receive full credit.)
When two atoms of chlorine and iodine join together to form a covalent bond, their outermost electrons interact to form a chemical bond.
What is a Covalent bond?
A covalent bond is a type of chemical bond that involves the sharing of a pair of electrons between two atoms. Covalent bonds are formed when two atoms come together to share their electrons in order to reach a more stable electron configuration. As a result, the two atoms become bonded together by the attraction of their shared electrons.
The chlorine atom has seven valence electrons, while the iodine atom has seven as well. Both atoms will want to complete their octets, so the two atoms share their outermost electrons with each other. During the formation of the covalent bond, the chlorine atom will donate one of its electrons to the iodine atom, while the iodine atom will donate one of its electrons to the chlorine atom. This sharing of electrons allows the two atoms to form a single bond and fill their octets, forming a covalent bond.

Lattice energy is a measure of the strength of the electrostatic attraction between the positively charged cations and negatively charged anions in an ionic compound. The greater the lattice energy, the stronger the electrostatic attraction and the more stable the compound.The most common method for determining lattice energy is the Born-Haber cycle. This method uses thermochemical data of the individual steps in the formation of an ionic compound to calculate the lattice energy. However, it is often impractical to use this method in a test environment, so a more practical method that is used to compare lattice energies of different compounds is the use of the Coulomb's law which relates the lattice energy to the charge product of the cations and anions and the distance between them.

What is the total reduction potential of a cell in which sodium (Na) is reduced and zinc (Zn) is oxidized
The total reduction potential of a cell in which sodium (Na) is reduced and zinc (Zn) is oxidized -1.95 V.
The tendency of a chemical species is to be reduced, expressed in volts under normal conditions, is known as the standard reduction potential.
The standard reduction potential belongs to the group of potentials known as standard electrodes or standard cells. The difference in voltage between the cathode and anode is known as the standard cell potential. The standard sodium reduction potential is -2.71V. Zinc has an average reduction potential of -0.76 V. Therefore, the overall reduction potential is 1.95 V.
