Answers

Explanation:

Lactase breaks down only lactose in food in our body can absorb it not maltose and sucrose as enzymes are specific in nature.

what are the properties of an enzyme ?

Enzymes are protein which act as a catalysts and speed up the rate of biochemical reactions with out changing the structure of the final product.

Enzymes can control the speed and specificity of the chemical reaction, and  the rate of biochemical reaction often influences enzymes and they can take place at a relatively low temperature; it   lower the activation energy.

The enzyme activity pH specific, that is at a particular pH, each catalyst is most active for example at PH 2 for pepsin, pH 8.5 for trypsin, for example.

Both enzymes have active sites which can activate biochemical reactions. It is soluble in water, dilute glycerol, NaCl, and dilute alcohol.

what is the function of circuit breakers and fuses?​

Answers

Answer:

Fuses and Circuit Breakers both serve the same purpose – which is to protect electrical circuits by preventing overloads that can cause fires. They both interrupt the flow of electricity, but in very different ways from each other. While a fuse is made of a piece of metal that melts when overheated, circuit breakers on the other hand, have internal switch mechanisms that can be tripped by an unsafe surge of electricity.

Fuses can be quicker for interrupting the flow of power, but when they melt they must be replaced; circuit breakers on the other hand just need to be reset. When comparing the two, we’ll take a look at some of the major advantages and disadvantages between fuses and circuit breakers to distinguish between them.

a/an ___ is a blood clot attached to the interior wall of a vein or artery.

Answers

Answer: a thrombus

A thrombus may also form in your heart

A thrombus is a blood clot attached to the interior wall of a vein or artery, which is option a. So the correct option is option a, as thrombus formation occurs when blood coagulation factors are activated and form a clot within a blood vessel.

Thrombi can occur in veins (venous thrombosis) or arteries (arterial thrombosis). In veins, a thrombus can lead to deep vein thrombosis (DVT), which commonly occurs in the lower extremities. If a thrombus dislodges from its site of origin and travels through the bloodstream, it is called an embolus, and it can potentially cause an embolism in another location. So the correct option is option a.

Two three-carbon molecules are converted into two Folecules of pyruvate as four

Answers

The correct order of glycolysis reactions is:

Two phosphate groups from two ATP molecules are joined to glucose.Two NADP molecules are converted into two NADH molecules.A six-carbon molecule is broken down into two three-carbon molecules.Two three-carbon molecules are converted into two molecules of pyruvate as four  molecules of ATP are produced.

During glycolysis, the glucose molecule is converted to Glucose-6-phosphate as a result of phosphorylation. The phosphate group from ATP is joined to the glucose molecule by an enzyme known as hexokinase.

The glucose-6-phosphate then undergoes isomerization to become fructose-6-phosphate which is then phosphorylated again by the hexokinase enzyme to become fructose-1,6-biphosphate.

An aldolase enzyme converts fructose-1,6-biphosphate to one molecule of glyceraldehyde-3-phosphate and one molecule of dihydroxyacetone phosphate. The latter is then converted to another molecule of glyceraldehyde-3-phosphate.

A dehydrogenase enzyme converts glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate with NADH being generated from the reduction of NAD+.

A kinase enzyme then converts 1,3-bisphosphoglycerate to 3-phosphoglycerate with ATP being generated from ADP. A mutase enzyme quickly converts the 3-phosphoglycerate to 2-phosphoglycerate while an enolase enzyme converts the latter to phosphoenolpyruvate.

Finally, a pyruvate kinase enzyme converts phosphoenolpyruvate to pyruvate with another ATP being generated.

What is Milton Erickson?

He is widely known for his pioneering work in the field of hypnosis. He believed that hypnosis is a form of communication between the hypnotist and the subject and that it involves a process of "roleplay" in which both parties take on certain roles or identities. In this sense, the hypnotist takes on the role of a facilitator or guide, helping the subject access their own inner resources and abilities. The subject, on the other hand, takes on the role of an active participant in the hypnotic process, using their own imagination and creativity to bring about positive changes in their thoughts, feelings, and behaviors.
