Biochemistry

The physical property of water is that it has two hydrogen atoms bonded to one oxygen atom. Water is odorless, tasteless and looks colorless in small quantities. Its boiling point is 100 degrees Centigrade and freezing point is 0 degrees Centigrade.

ER stands for endoplasmic reticulum. In Latin, reticulummeans "little net". ER surrounds the nucleus and comes in two forms: rough (ribosomes embedded in membrane) and smooth (no ribosomes).

Ada Lovelace, daughter of Lord Byron, is considered the "Mother of the Computer," due to her work with Charles Babbage. Known for her intelligence, Ada loved science and invention. The notes she took on the computer are considered to be the first algorithm, thus making her the first computer programmer.

A chaotropic salt is a salt that disrupts stabilizing intra-molecular forces such as hydrogen bonding. They the structures of biomolecules as proteins and nucleic acids.

It will make hydrophobic proteins more soluble in water.

Examples: magnesium chloride, lithium acetate, lithium perchlorate.

Non-living entities such as rocks, air, or water cannot metabolize nutrients as they lack the necessary biological processes and machinery to utilize and break down organic molecules for energy. Metabolism is a characteristic of living organisms that enables them to convert nutrients into energy through various biochemical pathways.

Dibasic potassium phosphate buffer is a solution commonly used in laboratories to control the pH of a reaction or a sample. It consists of a mixture of potassium dihydrogen phosphate (KH2PO4) and dipotassium hydrogen phosphate (K2HPO4) in specific ratios to maintain a stable pH. This buffer is especially useful in biochemical and molecular biology experiments.

Qualitative observation.

a) Increasing the concentration of KI would increase the slope of the curves due to the higher concentration of reactants affecting reaction rates. b) The rate of the reaction would likely increase with the higher KI concentration, as there are more reactant molecules available to interact. c) The numerical value of the rate constant, k, may change due to the altered reaction conditions, such as concentrations. The new k value would reflect the change in the rate of reaction caused by the change in KI concentration.

Lipid molecules are hydrophobic because they consist of long carbon-hydrocarbon backbones and contain only a small amount of oxygen.

Electrophoresis for nucleic acids (RNA and DNA) works by separating segments by their size. This is possible because RNA and DNA are negatively charged, so will move towards the positive charge applied to one end of the gel.

The different segments separate because small fragments of RNA or DNA are able to move more quickly through the gel than larger fragments.

Monosaccharides like glucose and fructose are considered substrate molecules that can be broken down during metabolic processes. Disaccharides like sucrose and lactose can also serve as substrates for enzymes that break them down into simpler monosaccharide units. Water is not a substrate molecule itself, but it may participate in hydrolysis reactions that break down carbohydrates.

Vitamins are essential nutrients that play a crucial role in various bodily functions such as metabolism, immune system support, and cell production. They help regulate processes like growth, digestion, and energy production, ensuring optimal health and functioning of the body. A deficiency in vitamins can lead to health problems and impair normal bodily functions.

Two types of secondary protein structure are alpha helix and beta sheet. Hydrogen bonds play a crucial role in maintaining these structures by forming between the carbonyl oxygen of one amino acid and the amide hydrogen of another, stabilizing the repeating patterns of amino acids in the helix or sheet. This helps in maintaining the overall shape and stability of the protein.

Yes, plant cells have chloroplasts, which are specialized organelles that contain chlorophyll and are responsible for photosynthesis. Photosynthesis is the process by which plants convert sunlight into energy to produce their own food.

Carbohydrates are the body's preferred source of energy for aerobic metabolism, providing quick energy for sustained physical activity. Fat is a more efficient source of energy and is used during lower intensity and longer duration activities for aerobic metabolism. In anaerobic metabolism, proteins can be broken down for energy during high-intensity, short duration activities when there is a lack of oxygen available. Balancing intake of carbohydrates, fats, and proteins is important for optimal performance in health-related fitness activities.

Carbohydrates are the body's main source of energy. They provide fuel for the brain, muscles, and organs to function properly. Additionally, carbohydrates play a role in maintaining healthy gut bacteria and fiber intake.

Yes, sperm does contain vitamin E as it is an essential antioxidant that supports sperm health by protecting them from damage caused by oxidative stress.

The suppressor reduces the background conductivity of the chemicals used to elute samples from the ion-exchange column. This improves the conductivity measurement of the ions being tested.

AGG, AGA, CGA, CGC, CGU, and CGG specify arginine.

The endoplasmic reticulum (ER) is a folded membrane that forms a network of interconnected compartments in the cytoplasm. It plays a crucial role in protein and lipid synthesis, storage, and transport within the cell. The ER is divided into rough ER, which has ribosomes on its surface for protein synthesis, and smooth ER, which is involved in lipid metabolism and detoxification.

The precursor produced in the dermal capillary is 7-dehydrocholesterol, which is converted to vitamin D3 (cholecalciferol) in the skin upon exposure to ultraviolet B light. Vitamin D3 plays a crucial role in aiding calcium absorption in the intestine, which is essential for maintaining bone health and overall mineral balance in the body.

AUG. The amino acid methionine. Bases read; adenine-uracil-guanine

Cherries are good for us in a lot of ways. They are low calorie, but are filled with nutrients, vitamins and minerals.

They contain anthocyanin glycosides; pigments that are especially concentrated in their skin and are known to have powerful anti-oxidant properties. Anthocyanins have been shown to act as anti-inflammatory agents and can potentially help chronic painful conditions like gout, arthritis, fibromyalgia and sports injuries.

Cherries are also rich in melatonin, which can possibly help neurosis, insomnia and headaches.

Cherries are a good source of the minerals potassium, iron, zinc, copper and manganese.

Cherries, especially tart cherries, are rich in the anti-oxidants lutein, zeaxanthin and beta carotene, which protect the body from free radicals.

Studies suggest that tart cherries may help fight cancers, neurological diseases and pre-diabetes.

A West Indian cherry called Acerola has exceptionally high levels of Vitamins C and A.
