Biochemistry

Most traits in our body are linked to two genes, one from our mother and one from a father. If you are a carrier for a genetic disease, it means that you have one defective gene and one "normal" gene.

The black lump is mostly carbon. Normally I would expect to find some partial combustion byproducts as well, since combustion is rarely 100% efficient.

because the catalytic reagents has higher activiation energy than stoichiometric reagent. NOTE a catalyst speeds up a reaction and is in no way affected during a reaction, a stoichiometric reaction is used up during the reaction

Chemical properties describe how a substance interacts with other substances to form new substances. These properties include reactivity with acids, bases, and other chemicals, as well as the ability to undergo chemical changes such as oxidation or reduction. The chemical properties of a substance are determined by its atomic and molecular structure.

The filter paper helps to evenly distribute the solvent vapor within the developing chamber, allowing for uniform separation of the components in the sample. It also acts as a medium for the sample to travel along with the solvent, facilitating the separation process in chromatography.

The five elements found in amino acids are carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur. These elements are essential for the structure and function of amino acids, which are the building blocks of proteins in living organisms.

Isocitrate, alpha-ketoglutarate, succinate, fumarate, and malate are tricarboxylic acids in the citric acid cycle.

The presence of unsaturated fatty acids in lipid bilayers helps plasma membranes resist freezing by preventing the lipid molecules from packing tightly together. Unsaturated fatty acids create kinks in the lipid tails, increasing membrane fluidity and allowing the membrane to remain flexible at lower temperatures.

Calcium and iron must be included on the Nutrition Facts label.

Glucose sugar; enzymatic processes such as photosynthesis have highly predicable outcomes.

In chemistry the splitting of water results in (2) H2 and (1) O2, yet in biochemistry the splitting of water involves H+ and OH-.

Geneticists call a trait that hides other traits a "recessive trait." When an individual has one dominant and one recessive allele for a specific trait, the dominant allele will be expressed, masking the effects of the recessive allele.

20 different amino acids are needed to synthesize most proteins. These amino acids can be combined in different sequences to create an almost infinite variety of protein structures and functions. Each amino acid has its own unique side chain that contributes to the overall properties of the protein.

Before the blood test, the patient must not eat or drink for four hours.The patient should eat and drink normally before the urine test.The technician handling the urine sample should be informed of any medications the patient is taking.

The lock and key analogy describes how enzymes interact with specific substrates. Like a key fitting precisely into a lock, enzymes have a specific active site that binds to a substrate of a particular shape, facilitating the chemical reaction. This specificity ensures that enzymes can catalyze specific reactions efficiently.

Carrots also do a lot for the stomach and eyes.

The liver stores glucose in the form of glycogen which is converted back to glucose again when needed for energy.

Human enzymes are most effective within a specific range of pH and temperature that optimizes their activity. This range is usually near the body's physiological conditions to ensure optimal enzyme function. Additionally, enzymes have specific substrate molecules they interact with, which allows for highly efficient catalysis of chemical reactions.

DNA in the nucleus of a cell is responsible for producing messenger RNA (mRNA) molecules that carry genetic information to the cytoplasm, where it can be used for protein synthesis. These mRNA molecules act as messengers between the nucleus and the rest of the cell, ensuring that the genetic information encoded in DNA can be translated into functional proteins throughout the cell.

Estrogen and progesterone are at their highest levels in the blood when the uterine lining is the thickest. These hormones play a crucial role in thickening the endometrium, preparing it for potential implantation of a fertilized egg.

Protease enzymes in biological washing powder can break down proteins, including those in silk fibers, potentially damaging the fabric. This can result in weakening or deterioration of the silk material. It is recommended to use a mild detergent specifically designed for delicate fabrics like silk.

Albumin and pepsin test positive for protein because they are proteins themselves. Proteins can be detected using various biochemical tests that target specific protein characteristics, such as their amino acid sequences or ability to react with certain reagents.

The anticodon sequences for the tRNA molecules that carry each amino acid are:

• Tyrosine: 3'-AUG-5'
• Leucine: 3'-CAA-5'
• Proline: 3'-GGC-5'
• Serine: 3'-AGU-5'
• Threonine: 3'-CGU-5'
• Stop codon: There is no tRNA anticodon for a stop codon as it signals the end of translation.

Protein synthesis primarily occurs in the cytoplasm of a cell, specifically on ribosomes. These ribosomes can be free-floating or attached to the endoplasmic reticulum. The process involves translating the genetic information from mRNA into a specific sequence of amino acids to build a protein.

Lipids are soluble in Bloor's regent (Ethanol and Diethyl ether in 1:2 molar ratio).
