Biochemistry

The absorption of glucose does not require energy. Glucose absorption occurs through facilitated diffusion, where glucose molecules move across the intestinal membrane down their concentration gradient with the help of transport proteins, such as GLUT2.

The dehydration of an alcohol produces an organic compound called an alkene. Alkenes are unsaturated hydrocarbons that contain a carbon-carbon double bond.

"The mechanism in which a release factor recognizes a stop codon is still unknown." Since anticodons are normally on the complementary tRNA. (The tRNA is what 'reads' the codons on the mRNA and ferries in the corresponding amino acid.) During translation stop codons are recognized by "release factors" that bind to the A-site on the ribosomes during translation.

Leucine is an essential amino acid that our bodies cannot produce, so it must be obtained from the diet. It is found in a variety of protein-rich foods such as meat, dairy, legumes, and nuts. Once consumed, leucine is absorbed in the gut and then used by the body for protein synthesis and energy production.

Fructose and fiber are two of the important product fruits deliver to the body but most importantly fruits are the best source of Vitamin C that we need often as it can not be stored in the body.

Iron is very important and can be found in liver, kidneys, dried fruit, beef and cocoa. It is required for the formation of haemoglobin as well as the formation of important muscles. Iron is stored in the liver. If iron is not eaten in a diet, anaemia, shortness of breath and tiredness are the deficiency symptoms.

The reaction between barium (Ba) and phosphorus (P) would form barium phosphide (Ba3P2) as the product.

Ensure nutrition drink was first introduced to the market in 1973.

It clears up scars and helps heal scabs faster

Thanks to a compound repellent that is found in corral, one new discovery comes of that shaped in pill form which may be taken orally to use for sunscreen. Another discovery is a pill that also works as a magnet which can be guided to an exact location, for instance to be place on a tumor and then released in pill form over the tumor.

Seeds develops into fruits and the ripening stage has many enzymes aiding the process. The hard, green,sour , mealy fruits ripen by the action of enzymes such as pectinases, amylases and ethylene oxide. The role of amylase is to convert the starch ( which imaparts a mealyness to unripe fruits) to glucose and hence impart sweetness.

The unique 3 base pair structure for an amino acid is called a codon. Codons are specific sequences of three nucleotides in mRNA that correspond to a particular amino acid during protein synthesis.

The antagonistic hormones are pairs of hormones that have opposite effects on the body. Examples include insulin and glucagon, which regulate blood sugar levels, and aldosterone and atrial natriuretic peptide, which control salt and water balance in the body.

Yes, a gel electrophoresis comparison of a mother and daughter would be expected to show more similarity than between a brother and sister. This is because a mother and daughter share more genetic material due to the maternal inheritance of mitochondria. Brothers and sisters, on the other hand, share only about half of their genetic material from their parents.

Well no you can not you have to order other ones because if the other vitamin are expire it would not help you anymore to have a good shape.

Of course you can. Since I left Canada many years ago and brought a large assortment of vitamins with me to Southeast Asia, I still have a few bottles not yet used up from that original supply.

I continue to use those old vitamins, though I have doubled my daily input to make up for the age of the vitamins that are left.

The strength of a vitamin is reduced as time goes by, but never to be completed empty of any benefit. The expiry date is just an educated guess of the limit of full strength.

To not continue using them would be a total waste of your money and against all common sense.

Curcin is a toxic protein found in the seeds of Jatropha curcas (physic nut) plants. It is heat-stable, highly toxic, and can cause severe gastrointestinal irritation and damage. Curcin acts by disrupting cell membrane integrity, leading to cell death.

The term "Saponification" is an indication of what this reaction originally was used for: making soap.

By boiling animal fat or lard with either potassium hydroxide or sodium hydroxide, the reaction, hydrolysis, produced glycerol and soap.

Enzymes follow a specific procedure called "lock and key" model, where they bind to substrates to catalyze reactions. Factors that affect enzyme activity include temperature, pH, substrate concentration, and the presence of inhibitors or activators. These factors can alter the enzyme's structure, affecting its ability to bind to substrates and catalyze reactions effectively.

Urease is an enzyme responsible for catalyzing the hydrolysis of urea into carbon dioxide and ammonia. It is produced by various bacteria and fungi and is important in the nitrogen cycle as it helps organisms utilize urea as a nitrogen source.

Cellulose is a type of complex carbohydrate found in plant cell walls. While humans lack the enzymes necessary to digest cellulose, some animals like cows and termites have specific gut bacteria that can break it down. This is why cellulose is considered a dietary fiber for humans, providing bulk to our diet and aiding in digestion.

it is used as a way of measuring how fast cells are dividing, defined as the doubling rate, and it is worked out with the following formula: k=(Log Nt - Log No)/ t x Log 2 this goes to the slightly easier form of; k= 3.32 x (Log Nt - Log No)/ t where k= growth rate constant Nt = number of bacteria at second time No = number bacteria at start t = time gone. (obvioulsy you take the logs of Nt and No in the formula)

To calculate the amount of Wang resin needed for solid-phase peptide synthesis, you first determine the target peptide length and use the substitution level of the resin to calculate the resin loading capacity. Multiply the loading capacity by the target peptide length to get the amount of resin needed. Adjust for excess if necessary based on your specific protocol.

Electron transport chains are located there are many different electron donors and electron acceptors. Reverse electron transport is the most important in prokaryotic electron transport chains.

Freezing temperature make ice of the water in bacteria and completely stop there metabolic activity. Enzymes do not work at freezing temperature as they have no scope for movement in solid ice. So there activity halted.

Restriction analysis is a technique used in molecular biology to cut DNA at specific sites using restriction enzymes. This method allows researchers to manipulate and study DNA sequences by creating fragments of different lengths. The resulting DNA fragments can be separated and analyzed to determine the sequence and size of the original DNA.
