Which of the following best describes the structure of a protein molecule?

Answers

Answer 1

Proteins are organic polymers made up of amino acids. Amino acids linked by peptide bonds form a polypeptide chain. One or more polypeptide chains are straight twisted into a three-dimensional shape to form a protein that best describes the shape of the protein molecule.

Proteins are located throughout the body: muscles, bones, skin, hair, and of course every single element or tissue of the body. It is part of many chemical reactions and enzymes that cause hemoglobin to contain oxygen in the blood. At least 10,000 unique proteins make and keep you where you are. Consuming high-protein ingredients has many health benefits, including faster recovery and/or harm after exercise. reduced muscle loss. Build muscle mass.

Proteins are the building blocks of muscle tissue. So, getting enough protein will help maintain muscle groups and promote muscle growth during electrical exercise. Severe protein deficiency can lead to edema, fatty liver, skin degeneration, increased severity of infections, and stunted growth in children.

The amount of food eaten by each organism is not equal to the total amount used by them as a result of heat lost through respiration etc.

What is Respiration?

This is referred to as the process in which an organism obtain energy which is usually in the form of ATP by the inhalation of oxygen and the exhalation of carbondioxide.

The amount of food eaten by each organism is not equal to the total amount used by them because activities such as respiration, excretion etc are responsible for the difference. In the trophic level, only 10 percent of the amount of energy is passed from one organism to another.

Zebra = 51698-26712-6602-8438 = 9946.

Hyena = 4682-544-733-814 = 2591.

In the alignment example, there are two places where the sequences differ. If there are a total of 100 bases in the sequence, what would be the percent identity between these two sequences?.

Answers

The percent identity between these two sequences is 98 %

Percent similarity" is the sum of two protein sequences' identical and comparable matches. However, studying the sequence identity shared by two protein sequences rather than the similarity is often more informative. There are several definitions of how connected (similar) two amino acid residues are to one another. Because there is no uniform definition of percent sequence identity, the pid function can be computed using any of the following functions:

PID1:

100 * (identical positions) / (aligned positions + internal gap positions)

PID2:

100 * (identical positions) / (aligned positions)

PID3:

100 * (identical positions) / (length shorter sequence)

PID4:

100 * (identical positions) / (average length of the two sequences)

Therefore pid2: 100 * (98/100)

=100 * 0.98

=98%

Therefore, the sequences can be said to be 98% identical.

During chemiosmosis, hydrogen ions accumulate in the ______ of the mitochondrion to create a large electrochemical gradient for aerobic cellular respiration.

Answers

During chemiosmosis, hydrogen ions accumulate in the intermembrane space of the mitochondrion to create a large electrochemical gradient for aerobic cellular respiration.

The concentration of hydrogen ions in the intermembrane space is higher than in the matrix as a result of the pumping of hydrogen ions through the inner membrane. As a result of this chemiosmotic gradient, the ions move back over the membrane into the matrix, where their concentration is lower, as a result of this chemiosmotic gradient.

The intermembrane gap is pumped with protons (H+) during this process. Protons flow through ATP synthetase in the inner membrane as a result of the gradient formed by the high proton concentration in the intermembrane gap and the low proton concentration in the matrix.

During cellular respiration, ATP is created via a process called chemiosmosis. Protons migrate through certain channels during chemiosmosis from the inner to the outer compartment of mitochondrial membranes.

Curare (tubocurarine, TUBARINE) is a drug that has a high affinity for nicotinic receptors on skeletal muscle fibers but not neurons is an agonist and causes muscle relaxation.

Cholinergic receptors called nicotinic acetylcholine receptors (nAChRs) are found in the plasma membranes of certain neurons and on the postsynaptic side of the neuromuscular junction. Because they are ionotropic receptors, nAChRs do not depend on second messengers and are connected directly to ion channels.

One non-depolarizing muscle relaxant is Curare, which inhibits the neuromuscular junction's nicotinic acetylcholine receptor (nAChR), one of the two types of acetylcholine (ACh) receptors.

Essentially, a drone is a flying robot that may be remotely controlled or can fly autonomously utilizing flight plans that are managed by software, onboard sensors, and a global positioning system (GPS).

Rolling motion is defined as movement of a drone about its longitudinal axis. The drone will move to the left if two of the right propellers spin quickly. The drone will travel right if its two left propellers are spinning quickly.

The motion of the drone's head rotating around its vertical axis (to the left or right) is referred to as yawning. The drone will rotate counter clockwise if two right diagonal propellers are moving quickly. The drone will revolve counter clockwise if two of its propellers are running in a left diagonal at high speed.

The production of silver grew over the centuries, but when Europeans first went to America, silver began to be used in many new and different ways. By the 19th century, nearly 120 million troy ounces were being produced annually. Now, more than 5000 years after ancient cultures first began to mine this precious metal, an average of 671 million troy ounces is mined every year. In earlier times, silver was thought to have magical properties and it was considered to be useful in keeping bad spirits away. Nowadays, most people think of silver in relation to ornaments. But it is significant for its antibacterial properties too. The ancient Phoenicians kept water, wine and vinegar in silver vessels to ensure freshness. It is only recently, however, that scientists have discovered how silver works. Quite simply, silver destroys the ability of bacteria to form the chemical bonds which are essential to their survival. When bacteria and silver come into contact, the bacterial cells fall apart. Today, there are bandages and ointments that use silver as an active ingredient. Silver promotes the growth of new cells, which in turn increases the rate of healing. This makes silver especially valuable for treating burns and wounds. Another key use for silver is in the millions of water purifiers that are sold each year. Silver prevents bacteria from building up in filters so that they can work effectively. Research has shown that silver, together with oxygen, cleans water. This means that other chemicals, such as chlorine, do not have to be used. Silver is therefore starting to be added to water purification systems in hospitals, community water systems and swimming pools. Scientists hope that silver will be able to be used in helping to produce clean drinking water in countries where water-borne illness is a problem. Current research shows that this use of silver is an exciting development for the global water supply. In the past, silver was often used to decorate places of worship, and many people saw it when they went to pray. Today, there is probably much more silver around us, but we do not necessarily see it. For example, every time you travel in a motor vehicle you are surrounded by pieces of silver. Every electrical action in a modern car is activated with silver-coated contacts. Basic functions such as starting the engine and opening power windows .all need a special switch that has a silver covering. Another important feature for our driving safety is the silver-ceramic lines fitted into the rear window.
