Leucine biosynthesis occurs in a multistep pathway starting from 2-oxovalerate, and the final product of the pathway (leucine) inhibits the first enzyme involved in the biosynthetic pathway through a process called feedback inhibition. This enzyme inhibition occurs, regardless of whether or not the 2-oxovalerate substrate is bound in the active site of the enzyme. Describe what type of inhibitor leucine is and justify your response.

Answers

Answer 1

Answer:

it is a type of mixed inhibition referred to as 'non-competitive inhibition'

Explanation:

Mixed inhibition occurs when an inhibitor binds to the enzyme in a site different from the active site where the substrate binds (i.e., the allosteric site). The term 'mixed' is because this inhibition is a mixture of competitive inhibition, where the inhibitor competes with a substrate to bind to the enzyme, and uncompetitive inhibition, where the inhibitor binds only to the complex formed between the enzyme and its substrate. In competitive inhibition, the maximal velocity of the reaction (Vmax) does not change, whereas the apparent Km (i.e., the concentration of substrate which permits the enzyme to achieve half Vmax) increases. ​Moreover, in non-competitive inhibition, the Km does not change, whereas the Vmax decreases. Non-competitive inhibition is a special type of mixed inhibition where the apparent Vmax (V app-max) is reduced, while the Km of the enzyme is unaffected.

ASAP Name one challenge we need to overcome by using solar panels

Answers

Answer:

It actually Polutes the enviornment more to own solar panels. This Is caused by the production and the dismemberment of the way its made.

Explanation:

Solar panels are composed of photovoltaic (PV) cells that convert sunlight to electricity. When these panels enter landfills, valuable resources go to waste. And because solar panels contain toxic materials like lead that can leach out as they break down, landfilling also creates new environmental hazards. The potential environmental impacts associated with solar power—land use and habitat loss, water use, and the use of hazardous materials in manufacturing—can vary greatly depending on the technology, which includes two broad categories: photovoltaic (PV) solar cells or concentrating solar thermal plants (CSP).

B)
Glucose and oxygen gas have higher energy levels compared to water and

C)

dioxide and oxygen gas.

D)
Glucose and oxygen have a lower energy level associated with them
compared to carbon dioxide and water.

Answers

Answer: The answer is B I just took the quiz

Explanation:

Glucose and oxygen gas have higher energy levels compared to water and carbon dioxide is accurately compares the products and the reactants with regards of photosynthesis.

What is Photosynthesis?

Green plants and certain other organisms convert light energy into chemical energy through a process called photosynthesis. Light energy is gathered and utilised during photosynthesis in green plants to change water, carbon dioxide, and minerals into oxygen- and energy-rich organic molecules.

It is impossible to overstate the role that photosynthesis plays in sustaining life on Earth. There would soon be little food or other organic materials on Earth if photosynthesis stopped. The majority of life would vanish, and eventually, the atmosphere of Earth would contain almost no gaseous oxygen.

Only chemosynthetic bacteria, which can use the chemical energy of specific inorganic substances and are not reliant on the conversion of light energy, would be able to survive in such an environment.

Therefore, Glucose and oxygen gas have higher energy levels compared to water and carbon dioxide is accurately compares the products and the reactants with regards of photosynthesis.

The precipitation that fell at this

Answers

Answer:

in snow form because the weather was mostly below water's freezing point, so it would snow instead of rain.

Explanation:

Maximum precipitation increases in the Antarctic region during the month of July because Antarctica has snowfall at that time of year due to its location at the earth's southern pole, so it has high precipitation in that area.

What is the significance of the Antarctic region?

It is the earth's southernmost continent, where the population is negligible, but there are many significant things available that are used for scientific research, such as oceanography and glaciology, as it has a wide variety of ecosystems, including penguins, seals, whales, and many other sea animals that are generally not found in the sea or in the river.

Type II survivorship curves Your answer: are characteristic of humans and elephants. typify a population in which all ages have an equal chance of survival. indicate a high mortality rate in the very young. show that very few young are produced, that each is given parental support, and that most individuals live a long life and die of old age. are typical of annual plants

Answers

Answer:

b. typify a population in which all ages have an equal chance of surviving. → YES

e. are typical of annual plants → YES

Explanation:

Different species have survival curves differently shaped. In general terms, there are three different survival curves.

Type I. Mortality often occurs at the end of the cycle, representing species with low mortality. Organisms exhibiting this type of survivorship curve have long cycles of life and high probabilities to survive until they are old enough. These species have few descendants and spend too much time and energy in parental care to ensure their reproductive success. Type II. The probabilities of dying are equals all along the cycle, at any age interval. The number of dead individuals remains constant from the beginning to the end of the life cycle. These species have reduced offsprings, and they ensure their reproductive success by providing some significant parental care. Type III. Significant mortality during the early stages of life. Only a few individuals reach the later life stages, getting to survive their first period of life. Survivors usually have a long life. These species produce big offsprings at the same time, but they provide little or no parental care. Their reproductive success relies on the number of descendants.

Type II survivorship curves:

a. are characteristic of humans and elephants → No, this is Type I curve

b. typify a population in which all ages have an equal chance of surviving. → YES

c. indicate a high mortality rate in the very young. → No, this is Type III curve

d. show that very few young are produced, that each is given parental support, and that most  individuals live a relatively long life and die of old age. → No, this is Type I curve

e. are typical of annual plants → YES

They tend to view morality in terms of the expectations of others and the rules that society has established.
