enzymes are specific they will only fit with certain substrates explain why lactase can digest lactose but cannot digest other sugars like maltose and sucrose

Answers

Explanation:

your small your small intestines can't absorb either lactose or maltoseyou use different enzymes to digest the two sugars lactase break down lactose why an enzyme called sucrase-isomaltase breaks down maltose because enzyme are so specific with regard to function you can't break down maltose with lactose or vice versa

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.

Two NADP molecules are converted into two NADH molecules.

Two phosphate groups from two ATP molecules are joined to glucose.

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

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.

The statement 'the leading strand is synthesized continuously and uses 1 RNA primer' is TRUE. It is replicated in the 3' – 5' direction.

The leading strand refers to the DNA template strand that is synthesized in the 3' – 5' direction during DNA replication.

The 3' – 5' direction that occurs during DNA replication is the direction of the replication fork.
