For a specific enzyme/substrate system, which condition will always result in an increase in Vo (assuming nothing else changes)?

1 answer:

8 0

<span>a decrease in Km and an increase in Vmax
km is the constant that relates how thick the volume of the substrate in terms of concentration when the speed is a large portion of the most extreme. They increment Km by meddling with the joining process that makes them stick together wit the substrate, however they have any effect with regards to Vmax since since the sticking process to ES did not occur</span>

What happens to the electrons in an ionic bond and a covalent bond?

irina1246 [14]

Answer:

In ionic bonding, atoms transfer electrons to each other. Ionic bonds require at least one electron donor and one electron acceptor. In contrast, atoms with the same electronegativity share electrons in covalent bonds, because neither atom preferentially attracts or repels the shared electrons.

Which of the following is a completely elastic collision? A. a ball rebounds against a wall, reversing its direction, but at onl

Dmitry_Shevchenko [17]

Answer:

Answer E.

For a collision to be completely elastic, there must be NO LOSS in kinetic energy.

We can go through each answer choice:

A. Since the ball rebounds at half the initial speed, there is a loss in kinetic energy. This is NOT an elastic collision.

B. A collision involving sticking is an example of a perfectly INELASTIC collision. This is NOT an elastic collision.

C. A reduced speed indicates that there is a loss of kinetic energy. This is NOT elastic.

D. The balls traveling at half the speed after the collision indicates a loss of kinetic energy, making this collision NOT elastic.

E. This collision indicates an exchange of velocities, characteristic of an elastic collision. We can prove this:

Let:

m = mass of each ball

v = velocity

We have the initial kinetic energy as:

KE = \frac{1}{2}mv^2 + 0 = \frac{1}{2}mv^2KE=21mv2+0=21mv2

And the final as:

KE = 0 + \frac{1}{2}mv^2 = \frac{1}{2}mv^2KE=0+21mv2=21mv2

What is the role of gluons?

igor_vitrenko [27]

The role of the gluons is to bind together the quarks that make up protons and neutrons. That is option D.

<h3>What are gluons?</h3>

Gluons are those particles found within an atom that are responsible for binding protons and neutrons together inside the nucleus of an atom.

The gluons are capable of binding the protons and neutrons together by holding together the quarks that makes up protons and neutrons.

These gluons are known to carry a color-anticolor charge which makes up the 9 types of gluons which include:

red anti-red,

red anti-blue,

red anti-green,

blue anti-red,

blue anti-blue,

blue anti-green,

green anti-red,

green anti-blue, and

green anti-green.

An atom is the smallest indivisible part of an element that can take part in a chemical reaction.

The proton is the positive particle of an atom which is found within the nucleus.

The neutron is the particle that is found in the nucleus of an atom which doesn't have any charge.

The__ model assigns to fixed orbits of defined energy. To move between orbits, electrons must emit or absorb _____ radiation

AURORKA [14]

Answer:

The Bohr model assigns to fixed orbits of defined energy. To move between orbits, electrons must emit or absorb electromagnetic radiation

Explanation:

In the Bohr model of the atom, the atom itself looks like a solar system.

In fact, at the center of the atom we have the nucleus, which contains protons and neutrons.

Around the nucleus, at a much higher distance, we have the electrons, negatively charged. The electrons move around the nucleus in fixed orbits, like the planets around the Sun.

According to Bohr's model, the electrons cannot live in the space between two orbits, but they must stay in one of these orbits. Each of these orbits is associated to a certain energy level: therefore, this means that the energies of the electrons in an atom are quantized, so they cannot take all possible values, but only some precise values.

Moreover, according to the law of conservation of energy:

- When an electron jumps from a lower energy level to a higher energy level, it must absorbs energy, and this energy is absorbed in the form of electromagnetic radiation (a photon) whose energy is equal to the difference in energy between the two levels

- SImilarly, when an electron jumps from a higher energy level to a lower energy level, it releases energy, in the form of electromagnetic radiation (a photon) whose energy is equal to the difference in energy between the two levels.
