Biochemistry

The messenger RNA or mRNA.

Proteins (enzymes) are molecules that are build up by amino acids. Activity of an enzyme is largely sspecifi to its three dimensional (3D) structure. The active site of an enzyme where substrate is converted to product is the crucial region that carry out catalysis. Any conformational changes in these crucial regions will reflect tremendously on its activity (may abolish completely or increase the activity). Because change in active site will not accomodate the substrate thereby no product formation.

Threonine and isoleucine exist as diastereomers of each other. They differ in the configuration at one chiral center, resulting in non-superimposable mirror image structures.

Adding glucose to activate yeast cells provides a readily available energy source for the yeast to begin fermenting and growing. The glucose is metabolized by the yeast into carbon dioxide and alcohol, allowing the yeast to thrive and carry out its fermentation process. This activation step is crucial for ensuring a successful fermentation process in bread-making or brewing.

Is is possible to determine how many amino acids are present in th hydrolysate if you forgot to mark the position of the solvent front when you tested the hydrolysate of aspartame

The whole DNA strand is a double helix.

yes

They would be described as being complementary - as in complementary base pairing.

Potassium Iodide is a inorganic compound, where Catalase is a organic compound.

Tetrose is a four-carbon monosaccharide.

The name "tetrose" comes from "tetr-", meaning four, and "-ose", meaning sugar.

Examples are:

- erythrose

- erythrulose

- threose

Glucose. Glucose is oxidized and oxygen is reduced here.

That is -ase. Enzymes are one type of proteins; enzymes have groups too. Proteases are enzymes that break down proteins.

Everywhere. Different reactions are happening in different places. The sum of all these reactions keeps the cell alive.

Polarity is the reason why a solvent can dissolve a solute. An example is oven cleaner removing grease from a oven when water cannot. Also water is know as the universal solvent because of its abundance and the fact that a lot of things we want to dissolve are polar molecules.

An aquatic environment's water CHEMISTRY refers to the amount of dissolved salts, nutrients, and oxygen in the water.

If you are in Mr. Sarau's class...nice going. haha

the second to last carbon n a chain

~Also known as the last chiral centre.

~Given to the highest numbered carbon.

The recommended dietary allowance (RDA) for protein is around 0.8 grams per kilogram of body weight. So, a person weighing 70 kg would need approximately 56 grams of protein per day. However, individual protein needs can vary based on factors like age, activity level, and overall health.

In a eukaryote, the DNA is to be found in the cell's nucleus.

Melatonin is the hormone that is thought to act as a sleep trigger and is associated with regulating circadian rhythms. It is also linked to seasonal affective disorder (SAD) as lower levels of sunlight can lead to decreased melatonin production, potentially contributing to mood changes in some individuals.

The amino portion of an amino acid is formed by a nitrogen atom attached to two hydrogen atoms, which together form an amino group (-NH2). This nitrogen atom is always bound to the alpha carbon of the amino acid's backbone.

Anti enzymes or enzyme inhibitors, are substances which inhibit counteracts the action of an enzyme.

Sugars that are monomers are called monosaccharides, which are singe (simple) sugars like glucose, fructose, and galactose. However, lactose is a disaccharide (double sugar) composed of galactose and glucose bonded together.

Cell disruption is the process of breaking open cells to release their contents, such as proteins, nucleic acids, and organelles. This is often done to extract specific cellular components or to study the internal contents of the cell. Methods of cell disruption include physical techniques like sonication and homogenization, as well as chemical methods like using detergents or enzymes.
