Answer:

Enzymes are one kind of protein which functioning as catalyst  that speed up reactions by lowering activation energy.Enzyme accelerate a reaction without altering its chemical equilibrium.

Explanation:

Energy which is required for  start a biochemical reaction is called activation energy.Activation Energy helps to jump and start a thermodynamically favorable reactions.

Enzymes can  many  way to its activation energy.

1. The enzyme may hold the substrates in such a way as to distort the substrate bonds closer to their form in the transition state. This reduces the amount of energy needed to complete the transition.

2.Enzyme create a charge distributor which opposite of transition state his lowers the energy of the transition state and decreases the activation energy.

3.The enzyme may reduce the reaction entropy   by bringing substrates together in the correct orientation to react.

4. The enzyme may provide a completely different chemical pathway for the reaction. It may form new bonds in the ES complex that would be difficult to form without the enzyme.

Outline why proteins are considered to be important biological molecules
Rasek [7]

proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macro molecules. the functions of proteins are very diverse because there are 20 different chemically distinct amino acids that form long chains, and the amino acids can be in any order. For example, proteins can function as enzymes or hormones.

Why did the petri dish get warm when hydrogen peroxide and liver were combined?
maks197457 [2]

Answer: The bubbles will form due to the liberation of oxygen gas and white spots will develop on the liver.

Explanation:

The liver is a vital organ, its function is to metabolize the toxins into less harmful metabolites, that are excreted out of the body.

The catalase is one of the enzymes that participate in the metabolic activities of the liver. In the given condition, when hydrogen peroxide and liver were combined. The catalase enzyme breaks down the hydrogen peroxide into water and oxygen. In this reaction, the oxygen gas is liberated, in the form of bubbles and this reaction produces white colored foam which later leaves white spots on the liver.

Which of the following is an example of conduction?
wlad13 [49]

Answer:

C

Explanation:

In conduction, heat moves from areas of more heat to areas of less heat by direct contact. In the atmosphere, conduction is more effective at lower altitudes where air density is higher.

4. At what point was the solution in beaker ""B"" neutralized?
Marina86 [1]

Answer:

Explanation:

This is called the equivalence point. That is the exact point during titration where the relative amounts of each substance in the chemical reaction of titration become well defined by the coefficients in the balanced chemical equation used for expressing the kinetics of reaction.  

A titration is an experimental set up   with a controlled acid-base neutralization reaction.it is used to determine the unknown concentration of an acid or a base.  

Acids and bases neutralize each other, forming a salt and water. Basically, a strong acid-strong base neutralization gives  a neutral solution with a pH of 7.
