Fill The Blank?when two amino acid monomers are positioned so that the carboxyl group of one is adjacent to the amino group of the other, they can be joined through a __________ reaction.

Answers

Answer 1

When two amino acid monomers are positioned so that the carboxyl group of one is adjacent to the amino group of the other, they can be joined by condensation reaction

A peptide bond can also be said as an amide bond and it is formed by the alpha nitrogen of one amino acid and the carbonyl carbon of the second. Peptide bonds are formed during translation process in which the bonds are formed from the amino(N) terminal to the carbon terminal(C) by removal of one water molecule and then catalyzed by RNA. Electron sharing in the amide bond prevents the rotation of the bond by delocalization. So the bond is fixed in one plane. Conformational flexibility of the peptide bond results as entirely from the rotation of the two bonds of the axis.

What is the difference between adrenergic vs cholinergic?

Answers

Adrenergic and cholinergic are terms used to describe two different types of neurotransmitters and receptors in the nervous system.

Adrenergic refers to the neurotransmitter called epinephrine (also known as adrenaline) and norepinephrine (noradrenaline), which are released by the sympathetic nervous system. These neurotransmitters bind to adrenergic receptors, which are located on many different types of cells throughout the body. Adrenergic receptors are classified into two main types: alpha-adrenergic receptors and beta-adrenergic receptors. When these receptors are stimulated by epinephrine or norepinephrine, they can cause various physiological responses, including increased heart rate, blood pressure, and respiration, as well as increased glucose release from the liver. Cholinergic, on the other hand, refers to the neurotransmitter called acetylcholine, which is released by the parasympathetic nervous system and some neurons in the central nervous system. Cholinergic neurotransmission is involved in many physiological processes, including muscle contraction, heart rate regulation, and memory formation. In summary, adrenergic and cholinergic refer to different types of neurotransmitters and their respective receptors, which play important roles in regulating various physiological processes in the body.

Which is more harmful to the Earth, human overpopulation or over consumption of natural resources?

Answers

Both human overpopulation and overconsumption of natural resources are major challenges facing the Earth today, and they are interconnected.

What is Earth?

Earth is the third planet from the Sun and is the only known planet to support life. It is the fifth-largest planet in our solar system and has a diameter of about 12,742 kilometers (7,918 miles). Earth is unique in that it has a complex and diverse biosphere that supports a wide range of living organisms, including humans. The Earth is composed of several layers, including the crust, mantle, and core. The crust is the outermost layer, and it is made up of solid rocks and minerals. The mantle is beneath the crust and is composed of hot, molten rock. The core is at the center of the Earth and is made up of iron and nickel.

The Earth is surrounded by an atmosphere, which is composed of nitrogen, oxygen, and other gases. The atmosphere protects the planet from harmful radiation and regulates the temperature and climate.

Here,

Human overpopulation refers to a situation where the number of people living in a given area exceeds the capacity of that area to sustain a comfortable and healthy life. Overpopulation puts a strain on natural resources, such as water, land, and food, and can lead to environmental degradation, loss of biodiversity, and pollution.

Overconsumption of natural resources, on the other hand, refers to a situation where humans consume natural resources at a rate that exceeds the Earth's capacity to replenish them. This can lead to depletion of natural resources, such as forests, water, minerals, and fossil fuels, and can contribute to climate change and other environmental problems.

In general, both overpopulation and overconsumption contribute to environmental problems and can be harmful to the Earth in different ways. Ultimately, the best way to address these challenges is to promote sustainable practices and policies that balance human needs with the health of the planet.

what is definition of evolution in biologi?

Answers

When new generations of an organism population replace older ones, the heritable features of the population change through evolution. Not individual organisms, but populations of organisms, evolve.

The change in the heritable traits of biological populations over multiple generations is referred to as evolution in biology. Genes, which are transmitted from parent to offspring during reproduction, express themselves in the form of certain traits. As a result of genetic recombination and mutation, variation frequently exists within a particular population. As evolutionary mechanisms like natural selection and genetic drift work on this variety, they cause specific traits to become more or less prevalent within a population. This is when evolution happens. The evolutionary pressures that determine whether a trait is common or rare within a population are always shifting, which causes a change in heritable traits to emerge through time. At every level of biological organization, biodiversity has been created as a result of this evolutionary process.

The articular hyaline cartilage on the end of an adult long bone arises from the mesoderm germ layer during embryonic development.

The mesoderm germ layer forms the limb buds, which later develop into the long bones of the body, during embryonic development. Hyaline cartilage, which acts as a template for bone production, covers the developing bones as they grow.

By a process known as endochondral ossification, the hyaline cartilage is gradually replaced by bone tissue as the bones expand. The articular hyaline cartilage at the ends of the bones, on the other hand, is still there and provides a smooth surface for joint motion.

Overall, the production of long bones is a complicated process that involves several stages of cartilage and bone development.

This enzyme uses 0.333 times as much substrate concentration as it can at its 25% maximal rate.

The connection between substrate concentration and Km

In actuality, Km is the substrate concentration at which the enzyme may accomplish half of Vmax. Because Km is a constant, raising the substrate concentration has no impact on it. An enzyme with a high Km has a poor affinity for its substrate and needs a larger concentration of substrate to achieve Vmax. The substrate concentration Km is equivalent to the substrate concentration at which the enzyme-catalyzed reaction proceeds at a rate that is half that of the maximum reaction rate.

V₀=Vmax(5)/5+Km

v₀/Vmax=5/5+km
