Biochemistry

Fruits and vegetables are some of the best food sources for water-soluble vitamins like vitamin C and certain B vitamins. Citrus fruits, bell peppers, leafy greens, and berries are particularly high in these vitamins. Additionally, fortified cereals and whole grains can also be good sources of certain B vitamins.

You can usually find old gate question papers on the official GATE website, various educational websites, or by joining online forums and communities dedicated to GATE exam preparation. Some coaching centers also provide previous year question papers as study material.

B-12 refers to a group of cobalt-containing vitamer compounds known as cobalamins: these include cyanocobalamin (an artifact formed as a result of the use of cyanide in the purification procedures), hydroxocobalamin (another medicinal form), and finally, the two naturally occurring cofactor forms of B-12: 5-deoxyadenosylcobalamin (adenosylcobalamin-AdoB-12), the cofactor of Methylmalonyl Coenzyme A mutase (MUT), and methylcobalamin (MeB-12), the cofactor of 5-methyltetrahydrofolate-homocysteine methyltransferase (MTR).

The term B-12 may be properly used to refer to cyanocobalamin, the principal B-12 form used for foods and in nutritional supplements.[1]

glycogen contains many branches of glucose molecules and acts as a storage of energy. Glucose molecules are cut off and used for energy. Because glycogen is so widely branched, glucose can be cut off from many of the branches simultaneously instead of one at a time. If it were one at a time as would be expected in a single, straight chain, we wouldn't be able to produce as much energy as quickly.

The length of the thick filament is the A band. The A band contains both thick and thin filament because they are overlapping each other.

The H band is thick filament only, however, it only covers a portion of width of the thick filament.

A banana ripening chamber is a specially designed room or container that controls temperature, humidity, and airflow to accelerate the ripening process of bananas. It helps ensure that bananas reach the desired ripeness level before they are distributed to consumers.

Some examples of solutes that do not dissolve when warmed include lead sulfate, barium sulfate, and strontium sulfate. These compounds have low solubility in water and do not readily dissolve with an increase in temperature.

A natural buffer is a system that helps maintain a stable pH level in the environment by absorbing or releasing substances. Examples include wetlands, mangrove forests, soils, oceans, and carbonate minerals.

Proteins are the primary macromolecules that can act as enzymes. They catalyze biochemical reactions by lowering the activation energy needed for the reaction to occur. Other macromolecules like RNA can also exhibit enzymatic activity, known as ribozymes.

The embryo gets its nutrition from the yolk sac, which is an early source of nutrients and blood supply. This provides essential nutrients for the embryo's development before the placenta and umbilical cord are fully formed.

Its standard name is, Nitrogen(III) Oxide.

The overall purpose of the Calvin cycle is to convert carbon dioxide from the atmosphere into glucose, a form of energy storage used by plants. This process occurs in the chloroplasts of plant cells and is essential for the growth and development of plants.

The question cannot be answered unambigously based on the information given, since the number depends on how long the chains at each branching point are. If there is one glucose substituent per branching point, the no. of glucose molecules used for the substitution is found by iteration starting by 60000/12 = 5000, but 55000/12 = 4583. Hence the average is where the ends meet: That is about 4791 substituents (depending on how numbers are rounded up or down), which gives 4791 non-reducing ends + 1 from the "backbone = 4792. If there are two glucose substituents per branching point, the no. of branching points, and hence the no. of reducing ends will decrease to about a little less than half of this number because more glucose monomers are "consumed" in the branching chains and the backbone chain will in turn be shorter resulting in fewer possible branching points. However, each branching chain will only have one non-reducing end, and the backbone will stil have only one non-reducing end! :-) Nice question though - I can add that if there is only one large molecule containing all these 60000 glucose monomers there will be only one reducing end no matter how many branching points there are.

Yes. Apples do indeed have electrons--and they also have protons and neutrons, since they consist of matter, which contains atoms--which, in turn, contain electrons, as well as protons and neutrons.

The most critical step of gram staining is the decolorization step as crystal violet stain will be removed from both G+ve & G-ve cells if the decolorizing agent(e.g alchohol ) is left on too long.

The enzyme Protease 'digests' proteins; and this contributes to the above process.

There are three mechanisms which govern hormone release; hormonal, humoral, and neural. Hormonal release means that one hormone will trigger the release of a second hormone. An example of this would be thyroid-releasing hormone from the anterior pituitary causing the release of thyroid hormone from, er, the thyroid. Humoral release is triggered by the presence of certain ions or nutrients in the blood stream. Insulin is an example of humoral release because it is triggered by the presence of glucose in the bloodstream. Finally neural release is a release caused by the nervous system directly. A good example of that would be the release of adrenaline (epinephrine) from the adrenal glands by the sympathetic nervous system.

Peptide bonds join the monomers in a protein's primary structure.

1)galvanic series is for both elements and alloys whereas emf series is only for elements

2)galvanic series tells about relative tendencies of corrosion whereas emf series tells about relative tendencies of displacement

Vitamin A is absorbed in the small intestine, primarily in the upper part called the duodenum. It is absorbed along with fats in the diet and requires bile and pancreatic enzymes for optimal absorption.

You could perform a simple enzyme activity assay. Mix the enzyme with its substrate and monitor the reaction rate over time using a spectrophotometer to measure any changes in absorbance or using a colorimetric assay to detect product formation. Compare the reaction kinetics with a control group lacking either the enzyme or the substrate to determine if the enzyme-substrate combination is necessary for the reaction to occur.

Vaseline is certified as non-carcinogenic therefor making the brand of petroleum jelly non toxic. There are side affect to using the product such as clogging pores in the skin, and making the skin dehydrated by blocking oxygen. The product only gives the appearance of hydration.

Carboxylic acids can be prepared by the oxidation of primary alcohols or aldehydes using oxidizing agents such as chromic acid or potassium permanganate. They can also be obtained by the hydrolysis of nitriles using a strong acid or base. Syndiotactic polymerization of styrene with carbon monoxide can also yield carboxylic acids.

Mammalian cells can survive at lower temperatures than body temperature, but extended exposure may lead to damage or death. Cold temperatures can slow down cellular processes, affect membrane fluidity, and disrupt protein function. Cells can adapt by activating survival mechanisms such as producing antifreeze proteins or increasing metabolic activity.
