Classify the enzyme inhibitors by giving the names, mechanisms, and effect on the kinetic parameters Km and Vmax.

Answers

Enzyme inhibitors are either competitive, uncompetitive or non-competitive inhibitors and have different effects on Km and Vmax.

What are enzyme inhibitors?

Enzyme inhibitors are substances which inhibit the catalytic activity of enzymes.

Enzyme inhibitors are classified into three:

Competitive inhibitors - compete with substrate for enzyme binding site. They have no effect on Vmax but increases Km.Uncompetitive inhibitors- bind to the enzyme–substrate complex. They decrease both Vmax and Km.Non-competitive inhibitors- bind to another site on the enzyme. They have no effect on Km but Vmax is decreased.

Therefore, the enzyme inhibitors are either competitive, uncompetitive or non-competitive inhibitors and have different effects on Km and Vmax.

Drag each tile to the correct box. Not all tiles will be used. One statement is an example of a scientific observation. Another statement is an example of a scientific explanation. Identify the correct statement for each category to illustrate how scientific explanations are inferred from scientific observations.

Answers

Statements 1, 3, and 6 are scientific observation while statements 2, 4, and 5 are scientific explanation.

What is a scientific observation?

A scientific observation can be defined as an active acquisition of knowledge (information) through one of the sense organs, while using scientific tools and instruments.

In this scenario, some examples of a scientific observation are:

"Cloning has the potential to significantly benefit a great many people, so it should not be considered immoral or risky.""The age, type, and composition of ancient rocks in western Africa are nearly identical to the age, type, and composition of rocks in eastern South America.""The rocks present in western Africa and eastern South America formed at the same place and at the same time."

What is a scientific explanation?

A scientific explanation can be defined as a type of statement that is used to provide adequate information on the reason for an event, process or phenomenon, especially after drawing an inference.

In this scenario, some examples of a scientific explanation are:

"The cloning of organisms is an exciting area of study, and more resources should be be devoted to it.""Even if modern organisms are found in ancient portions of the fossil record, this wouldn't challenge the theory of evolution in any way.""A scientist thinks that he might find serious inconsistencies in the fossil record if he conducts an excavation in a new location."

Lymph is collected from the body’s organs.

Answers

Lymph is a fluid similar in composition to blood plasma. It is derived from blood plasma as fluids pass through capillary walls at the arterial end.

The lymphatic system collects excess fluid that drains from cells and tissue throughout the body and returns it to the bloodstream, which is then recirculated through the body.

Spleen: This largest lymphatic organ is located on your left side under your ribs and above your stomach.

Evidence of evolution

Answers

Natural selection has to do with organisms being best suited for their environment surviving and reproducing more often.

What is natural selection?

It is a process by which living organisms evolve.

The natural selection theory was proposed by Darwin. It states that organisms with traits that enable them to adapt better to the environment survive better and contribute more to the future population.

In the process of reproduction, the adaptive traits are passed to future generations. Thus, the future generation would be made up of individuals with adaptive traits.

Weak individuals without the adaptive traits gradually fade off from the population.

Answers

More condensation nuclei, more cloud formation and precipitation are the results of spraying aerosols into the atmosphere.

What are the effects of aerosols on clouds?

Aerosols greatly influence clouds formation and its growth. Water droplets gather readily around particles which provides a particle-rich atmosphere that promotes cloud formation.

So we can conclude that more condensation nuclei, more cloud formation and precipitation are the results of spraying aerosols into the atmosphere.

(a) a prevailing wind coming from the North Pole

Answers

A prevailing wind coming from the North Pole would each type of prevailing wind have on the land it crosses.

What are the three different kinds of prevailing winds?

The trade winds, prevailing westerlies, and polar easterlies are the three predominant wind belts connected with these cells.

Although prevailing winds frequently come from the north sea and provide moisture to the land, they can also bring moisture to the land. There is no moisture or water involved when wind comes from a land location. This means that the winds bring more dry air into the atmosphere, reducing the likelihood of rain.

Explain how the process of natural selection can account for
the increase in frequency of the antifreeze protein gene in the
icefish population.

Answers

The antifreeze molecules allow icefish to live in subfreezing water by filling voids in existing small ice crystals and preventing the annexe of more ice molecules. Ice crystal development is thus effectively prevented.

Where are antifreeze proteins found?

Antifreeze proteins (AFPs) are natural antifreeze components initially seen in polar fish; AFPs can attach to ice and thereafter inhibit the development of the ice crystals. Fish can inhabit (−0.7 °C) of their blood serum by the integrity of AFPs.

4. Based on the wintertime La Niña weather map, what do you think Florida's temperature and precipitation would be like during a winter El Niño event?

Answers

If the La Nina occurs, the Jetstream will be further north during the event. This has to do with the chilly temperature in the Great Lakes.

What is La Nina?

Strong winds carry warm water towards Asia during La Nia episodes, causing upwelling along the west coast of the Americas. This means that in the Pacific, cold, nutrient-rich water rises to the top, pushing the jet stream northward.

In the winter, La Nina is associated with drier and warmer weather, which shifts to snowstorms in a northerly direction.

The lower southern region will have drier circumstances, while Florida will experience warmer than normal temperatures. As a result, Florida's winters will be moderate, with temperatures ranging from 5 to 18 degrees Celsius.

As a result, it will not experience the same conditions as the winter El Nino.

In an experiment, a snail was observed to have moved a distance of 0.5 meters in 2 hours. What rate of movement was observed in this experiment?

Answers

The rate of movement was observed in this experiment as 0.25 m/ hour.

How, explain your answer?

A rate of movement is essentially a speed measurement, where you divide the distance crossed from point A to point B by the time it took to do it.

o, we know the snail moved a total distance of 0.5 meters. that's our distance crossed.

We know that took 2 hours.  so we just have to calculate that:

0.5 meters / 2 hours  = 0.25 m/hour

Answers

Answer:

Active transport mechanisms require the use of the cell’s energy, usually in the form of adenosine triphosphate (ATP).

Explanation:

If a substance must move into the cell against its concentration gradient, that is, if the concentration of the substance inside the cell must be greater than its concentration in the extracellular fluid, the cell must use energy to move the substance. Some active transport mechanisms move small-molecular weight material, such as ions, through the membrane.

In addition to moving small ions and molecules through the membrane, cells also need to remove and take in larger molecules and particles.
