Biochemistry

Sucrose would not give a positive test with Fehling's reagent after hydrolysis because sucrose is a non-reducing sugar. During hydrolysis, sucrose is broken down into its monosaccharide components (glucose and fructose), which are reducing sugars and can react with Fehling's reagent to give a positive test for reducing sugars.

Not at all. mRNA is not involved in DNA replication as it is involved in transcription and translation.

The thyroid gland contains hormones in a colloid. Thyroxine and triiodothyronine are stored in the colloid in the thyroid follicles before being released into the bloodstream.

Some drawbacks of SDS page include:

1. Limited resolving power for proteins with similar sizes.
2. Inability to provide information on protein structure or function.
3. Difficulty in separating proteins with very high or low molecular weights.
4. Potential loss of biological activity during sample preparation.

Yes, the kcat value of catalase is typically much higher than that of other enzymes. Catalase is known for its efficient turnover rate, as it can decompose millions of molecules of hydrogen peroxide per second. This high kcat value reflects catalase's importance in protecting cells from oxidative damage.

it is because casein has an isolectric point at 4.6, milk has a pH of 6.6. Casein at this pH has a negative charge, when added with an acid, the phosphate group found in casein is protonated, and when the pH reaches to 4.6, then the casein would then be aggregated, becoming insouluble to milk

The first version was made in the 1950's which contained a high level of oestrogen and progesterone. But soon, there were side effects of oestrogen like blood clots. Therefore, the pill right now has a lower dose of oestrogen so that means lower side effects.

template for transcription. During transcription, RNA polymerase reads the DNA sequence and synthesizes a complementary mRNA strand using base pairing rules (A-U and G-C). This mRNA molecule then serves as a template for protein synthesis during translation.

An increase in Vmax suggests an increase in the maximum rate of an enzymatic reaction, indicating an enhancement in the enzyme's catalytic activity. This could be due to factors such as increased enzyme concentration, enzyme efficiency, or substrate availability. An increased Vmax can also indicate a higher affinity between the enzyme and substrate.

Amino acids are generally soluble in water due to their hydrophilic nature. However, the solubility of a specific amino acid can vary depending on its side chain properties. Some amino acids may have limited solubility in nonpolar solvents but are usually soluble in water.

Many plant and some animal cells use oil for energy storage .

1. Protein Anchor

2. Selectively Permeable Barrier

3. Energy Production

Enzymes in the cotyledon are typically activated by factors such as moisture, temperature, and pH levels. These factors help initiate the germination process by triggering the enzymes to break down stored nutrients in the cotyledon for the growing seedling to use.

Humans make glucose, fructose, and galactose, as these are monosaccharides that our bodies can produce. The others listed are not made by humans but are consumed through diet or supplementation.

Enzymes can be compared to a key that unlocks a door. They help speed up chemical reactions in the body by lowering the energy required for the reaction to occur, just like a key makes it easier to open a lock.

Glycogen and starch are two substances made from repeating units of glucose.

1. Substrate binding: The enzyme binds to its substrate.
2. Catalysis: The enzyme facilitates the conversion of the substrate into product.
3. Product release: The enzyme releases the product of the reaction.
4. Enzyme recycling: The enzyme returns to its original state to catalyze further reactions.

Most orchids have 2n = 38 chromosomes, but chromosome numbers can vary among different orchid species.

starch

Some stays around for a while so many polypeptide chains can be run from it, while other mRNA is degraded in the cytosol almost immediately by enzymes designed for the task. Depends on how much protein product is needed in the representation of the particular mRNA.

Good question but no simple answer. Differentiation occurs for many more reasons than a few genes and yet genes can have a considerable effect on the outcome. The location of the cells during cell division/blastulation/gastrulation have a significant effect on differentiation as Mesoderm, Endoderm and Ectoderm form.

Find a great developmental biology book that has a strong genetics section, a few thousand pages will give you a good start.

If the active site of an enzyme is continuously filled and the maximum enzyme rate has been reached, adding more substrates will not increase the rate of the reaction. This is because all available enzyme active sites are already saturated with substrates, so increasing substrate concentration will not result in more enzyme-substrate complexes being formed.

NH is a polar covalent bond. The difference in electronegativity between nitrogen and hydrogen causes the electrons to be unequally shared, resulting in a partial negative charge on the nitrogen atom and a partial positive charge on the hydrogen atom.
