Imagine that you are observing an enzyme-catalyzed reaction in the lab. Every time you add more enzyme, the reaction rate increases proportionally until the reaction rate suddenly levels off. No other chemicals were added, and no modifications were made in the experimental setting. Why do you think the reaction rate stopped increasing?

Answers

The rate of reaction stops increasing because there is no substrate left to bound with an enzyme to increase the rate of reaction.

What is an enzyme?

An enzyme is a substance that increases the rate of reaction by catalyzing the reaction.

The enzyme is called a biological catalyst.

Enzyme work when it combines with the substrate of the reaction to make products.

When the enzyme is added, the rate of reaction increase because it fastens the reactions.

But when the substrate is converted into a product and there is no substrate left to combine with enzyme the rate of reaction stop increasing.

Thus, The rate of reaction stops increasing because there is no substrate left to bound with an enzyme to increase the rate of reaction.

Answer:

All the substrates are bound to the enzyme, thats why the reaction rate stopped increasing.

Explanation:

Actually an enzyme works by binding a substrate molecule to its active site, producing a product  , resulting in an increase in the rate of reaction.

            Enzyme + substrate = Enzyme + product

Whenever enzymes are added , reaction rate increases as the substrates are being bound to the enzyme's active sites but then occurs a stage where further addition of enzyme cannot increase the reaction rate because all the substrates have bound to the enzyme and there are no substrates left.Hence the reaction rate stopped increasing.

Why do dead plants decompose slowly in marshes?

Answers

Marshes refers to a place which has low land and prone to floods. Since it is always wet, dead plants slowly decomposes on this area because it has lesser bacteria or decomposes that helps the plants to decompose faster. 

Which of the following affects the intensity of the combustion reaction ifs Bunsen burner ? A.)the temperature in the laboratory B.)the position of the Bunsen burner
C.)the amount of air that mixes with the gas stream

Answers

The amount of oxygen that mixes with the gas stream effects the intensity of the combustion reaction in Bunsen burner. The correct option among all the options that are given in the question is the last option or option "C". The increase in the amount of air mix will result in a flame that has a higher temperature.

Which is a disadvantage of using DNA technology?edible vaccines
phytoremediation
herbicide tolerance
gene transfer to nontarget species

Answers

Answer:

The answer is D. Gene transfer to non-target species.

Explanation:

Using DNA technology we have made several genetically modified crops called GM crops. But sometimes the transgenic trait or gene may effect the non-target species. For example Bt-crops were found damaging the soil health. These pest resistant Bt-crops release Bt toxin near the soil root zones. High levels of Bt toxin can affect the health of soil as well as the soil insects. Hence GM crops must be monitored for the effects on non-target species.

Answer:

The correct answer is: Gene transfer to non-target species. It is believed within the scientific field that these risks directly affect environmental impacts and need to be assessed on a case by case basis and recommended post-release ecological monitoring. 

Explanation:

Transgenic crops could possibly entail positive or negative indirect environmental effects through changes in agricultural practices such as pesticide and herbicide use and cropping patterns. Agriculture affects the environment it does not matter which type we are talking about. Then it is normal to conclude that the use of new genetic techniques in agriculture will also affect the environment.
