While studying enzyme kinetics in the lab, a scientist observed that the rate of a reaction involvingenzyme amylase increased as the concentration of starch increased. With further increase in starchconcentration, the amylase activity did not change. Why did this happen

Answers

Answer 1

Answer: B. This is because there were still active sites available for the starch substrate to bind to when the concentration was initially increased (the reaction will have been first order with respect to the concentration of starch). However, at a certain concentration, all the active sites of the enzymes will be full so there will be no active sites available for the starch molecules to bind to (the reaction is now zero order with respect to the concentration of starch). i need brainliest answer to rank up plzzzz help

Which of the following is a drawback to superconductors?-They perform well only at very low temperatures.
-They are made from extremely expensive materials.
-They have very few uses.
-They are dangerous to use.

Answers

The answer is the first option.

"They perform well only at very low temperatures."

Despite of advantages of Superconductors such as power and cost efficiency, these conductors have drawbacks. Semiconductors have restricted operation range of operating temperatures. They are required to work at very low temperatures.

Answer:

They perform well only at very low temperatures.

Explanation:

Define the two types of carbohydrates important to proper nutrition and name two foods where they can be found for each.

Answers

The two types of carbohydrates are simple sugars and complex carbohydrates.
Simple sugars are monosaccharides and disaccharides, meaning the contain one or two sugar units. Simple sugars are broken down quickly by the body and released for quick energy. Examples of simple sugar foods include table sugar, fruit juice and honey.
Complex carbohydrates are polymers formed by the simple sugars,or a lengthy sequence of sugar monomers that are joined together. Their complex structure means that they take longer to breakdown, digest and be absorbed into the body. Complex carbohydrates are often high in fiber. Examples of complex carbohydrates include whole grain products and vegetables.

Answer:

simple sugars and complex carbohydrates.

Explanation:

simple sugar can be found in fruit. Complex carbohydrates can be found in vegetables

Organisms are classified as fungi if they

Answers

Organisms are classified as fungi if they have chitin in their cell walls.

Fungi are eukaryotic organisms (such as yeasts and molds) that usually have chitins in their cell walls but no chlorophyll or plastids. Fungi may be unicellular or multicellular. Fungi do not photosynthesize but they are heterotrophs like animals. They get their food by absorbing dissolved substances and they usually reproduce by means of spores.

The cell theory states that all living cells come from pre-existing cells. If that's true then, how did the first cell originate?1 not enough information is given
2 Nature created the first cell.
3 The first cell originated spontaneously.
4 This postulate of cell theory is false.

Answers

Answer:

option 2 and 3 are seems to be correct.

Explanation:

according to our studies the options and 3 are seems to bee correct because the first cell was created by nature not by man or any other organism and the term spontaneously also look to be true. so my answer is that options 2 and 3 are correct.
