Cellular respiration converts the energy of fuel molecules to a form of energy that a cell can use to perform work. In an average day, most adult humans need to consume about 2,000 Calories to maintain their health. However, the exact amount of dietary Calories a person needs depends upon many factors, including the person's age, physical activity, size, and health. Foods that we consume vary greatly in their nutritional content and quality. A large hard-boiled egg, for example, has about 75 dietary Calories and contains about 70% of our recommended daily intake of cholesterol. A person eats one hard-boiled egg and digests the egg fully. During cellular respiration MOST of the Calories in the egg is converted to ________.

The main role of the ________ is to increase the binding ability of RNA polymerase to the lac operon promoter region.

Answers

Answer:

catabolite activator protein (CAP)

Explanation:

Catabolite activator protein (CAP) is a homodimeric transcriptional activator required for transcription initiation of catabolite-sensitive genes in Escherichia coli. CAP contains a ligand-binding domain at its N-terminus and a DNA-binding domain at its C-terminus. CAP activates transcription by binding at target DNA sites on promoter sequences, thereby enhancing the ability of the RNA polymerase to bind and initiate transcription. CAP binds cyclic AMP (cAMP) to increase CAP’s affinity to DNA and thus activates the transcription of genes for catabolism, such as the lactose (lac) operon genes (the lac operon is a set of genes that encode for enzymes taking part in lactose metabolism).

(Choice C)

(Choice D)
D
Largest fragment of DNA that traveled the slowest

Answers

Answer:

C) Smallest fragment of DNA that traveled the fastest

Explanation:

During this gel electrophoresis, DNA passes through a agarose obstacle course, where the poles opposite to wells are positively charged electrodes. Since DNA is negative in charge, when it is placed in wells and electric current is run, DNA will try to run towards the positive end.

Shorter DNA segments can easily  "wiggle" through the pores of the gel whereas, longer DNA segments need to do more "squeezing" to move down the gel.

Therefore, Band X in this figure is the shorter DNA segment as it move through the lane at a faster rate and reaches very far when compared to longer DNA segments.

Smallest fragment of DNA that traveled the fastest. So, the correct option is (C).

What is Gel electrophoresis?

Gel electrophoresis is defined as the technique that is used in laboratories to separate charged molecules such as DNA, RNA and proteins according to their size where the charged molecules move through a gel when an electric current is passed through it.

During gel electrophoresis, the DNA passes through an agarose barrier course, where opposite poles of the wells are positively charged electrodes, so the DNA is negatively charged when it is placed in the wells and an electric current is passed through it. DNA will try to run towards the positive end.

Shorter DNA segments can easily "squeeze" through the pores of the gel, while longer DNA segments require more "squeezing" to move down the gel. Band X in this figure is the short DNA segment as it moves through the lane at a faster rate and reaches much farther than the longer DNA segments.

Thus, smallest fragment of DNA that traveled the fastest. So, the correct option is (C).

Dominic made the table below to organize his notes about mixtures. A 1-column table. The first column labeled properties of mixtures has entries has no set composition, must have more than one state of matter, must have more than one substance. What mistake did Dominic make? The title should read “Properties of Solutions” because some mixtures do not have all of the properties listed. There is a definite recipe to make each mixture, so the composition of a mixture is set. Although it is possible to have more than one state, it is also possible to have only one state. A single substance can be used to make a mixture if the substance is composed of more than one element.

What is the name of the strategy that combines two plant proteins (grains and beans) to get all the essential amino acids

Answers

Answer:

Protein combining

Explanation:

The strategy involving the combination of two plant proteins to get all the essential amino acids is referred to as protein combining.

The practice of protein combining is common among vegans due to the general belief that a single plant-based protein does not contain all the necessary amino acids for the body. Thus, one would need to combine 2 plant-based proteins in order to get all the essential amino acids for adequate health.

Answer:

Multiaxial joint

Explanation:

Joint is understood as the set of structures that allow the union of two or more bones and / or cartilage with each other. The synovial joint is a union that is established between bones that have different articular surfaces. There are factors that determine the axes of space in which a joint can be mobilized, in such a way that uniaxial, biaxial or multiaxial joints are identified. The multiaxial joint is movements in around three axes or three degrees of freedom. These joints can perform any movement. This movement that is carried out in the three axes is called circumduction movement (in a circle). The movements that a synovial joint can carry out are sliding, extension, flexion, abduction, adduction, medial rotation, lateral rotation, circumduction, protrusion, retrusion, diduction, pronation, supination, inversion, eversion, among others.

Why do only certain cells respond to particular signaling molecules that are sent throughout the body

Answers

Answer:

The presence of appropriate receptor dictates which cells will be receptive to a particular signal.

Explanation:

Some cells only respond to certain molecules because they have receptors to accept those molecules. Hence, due to this, only some molecules can be accepted by the cells.

How does a particular cell accept the molecules?

Hormones are secreted by endocrine glands into the blood. The endocrine glands, such as the pituitary gland, secrete their hormones directly into the blood, but not all cells of the body can bind to the molecule and perform the cellular functions.

The cells' surface has receptors for molecules such as peptide molecules or polar hormones that can't directly enter the cell. Hence, they bind to the cell surface receptors and send signals with respect to those hormones.

A hydrophobic hormone can directly enter the cell as it can easily pass the plasma membrane. After entering the cell, it has some receptors in the nucleus or in the cytoplasm. This hormone can perform functions such as gene activation after binding with them.

Hence, after binding with receptors, they show their performance, and not every cell has the same receptors for a single molecule.
