Biochemistry

Add tubes to your centrifuge basket arranged as factors of the total number of spaces. For instance, if you have a twelve hole centrifuge, you can add tubes in every second hole, for six tubes in total; in every third hole for four tubes in total, in every fourth hole for three tubes in total; or every sixth hole for two tubes.

You can combine these factors one way to place five tubes in your centrifuge basket - a balanced array of two and a balanced array of three tubes.

As well as that, you can arrange the gaps in your centrifuge basket the same way, so you can have five , four, three or two tubes left out of a twelve hole basket.

In that way it is possible to place two, three, four, five, six, seven, eight, nine, ten or twelve tubes safely in a twelve hole centrifuge basket.

The part of cellular respiration in which glucose is broken down is called the glycolysis. The chemical energy to produce ATP come from the breakdown of carbon based molecules into the smaller molecules.

A disaccharide. An example of this would be sucrose, common table sugar.

After an enzyme performs its function, it can be reused to catalyze the same reaction repeatedly. Enzymes are not consumed or altered during the reaction, so they can continue to work until they are degraded or denatured.

DNA is deoxyribonucleic acid.

RNA is ribonucleic acid.

They are both nucleic acids.

They are the fundamental building blocks of any particular organism. These highly conserved molecules caries all the genetic information of one organism and past organisms. of the genetic information.

Body has got very large reservoir of fat, in which very large quantity of fat soluble Vitamins can be stored. Body has no mechanism to excrete these fat soluble vitamins as fat does not come in contact with any excretory organ like a pair of kidneys. It is stored in fat cells. If you give excess of water soluble vitamins, then they will be excreted by pair of Kidneys. Pair of kidney filters out about 180 litres of fluid/ day and through this excrete water soluble vitamins. Now it is easy to understand that why water soluble vitamins are not stored in body.

The shape of the active site is very important because it determines the efficiency of the specific enzyme. If an active site shifts, the substrate can no longer bind to an enzyme's active site, therefore causing inefficiency. We say that the enzyme is undergoing denaturation.

Citric acid is considered to be a weak acid.

If it is said more correctly, salt dissociates in water as it is an ionic compound and seperate into ions when mixed water. Subsequently, these ions create hydration spheres very rapidly. This is the reason for the observation of rapid dissolving of salt.

On the other hand, sugar has relatively large molecules which have covalent bonds. The only way sugar can dissolve in water is making hydrogen bonds with the -O-H groups it has. This takes a considerable time when compared to the dissociation of salt.

Vitamin C and B complex are both water soluble (ie hydrophilic), which is why a daily dose is recommended. Your body only uses what it needs in a day, and any excess in your body will be dissolved in water and excreted (this is why your urine is very yellow after taking a B complex, it's the excess B2 - riboflavin that is naturally yellow.)

Vitamins A, D, E, and K are all fat soluble (ie hydrophobic). The excess which is not used is stored in adipose tissue (fat cells) until needed. This is where people started saying you'll turn orange if you eat too many carrots: carrots contain beta-carotene which the body turns into vitamin A with bile salts.

So it is possible to get too much of the A, D, E, and K (though none are toxic at high levels except vit D - so watch out), but it is silly to take tablets with large amounts of vitamins B and C because you'll just excrete it!

In the duodenum there is pancreatic lipase. This is an enzyme that breaks down fats into small enough pieces that you can absorb it to use it for energy/fuel.

To be technical, fats in the duodenum are emulsified by bile (produced in the liver) and mixed micelles are formed (small "balls" of triglycerides, cholesterol, phospholipids, etc.). Pancreatic lipase will break down triglycerides in the mixed micelles into monoglycerides and free fatty acids. The enterocytes lining our small intestines will absorb monoglycerides and fatty acids.

It should do nothing to blue litmus, and it will turn red litmus a very soft purple, because it is barely basic

All enzymes are proteins. They are tertiary proteins

No, ATP (adenosine triphosphate) is not a neurotransmitter. It is a molecule that provides energy for cellular processes. Neurotransmitters are chemical messengers that transmit signals between neurons in the nervous system.

Through substrate level phosphorylation where a phosphate group is trasnferred directly from a high-energy moleculr to ADP by the action of an enzyme (demonstrated in glycolysis by pyruvate kinase and phosphoglycerate kinase enzymes); or through oxidative phosphorylation where a series of redox reactions generate a proton gradient that drives the production of ATP from ADP by ATP synthase (demonstrated by electron transport chains of mitochondria and chloroplasts).

Strong nuclear force

Non identical twins are formed when the mother releases two eggs and both those eggs are fertilised. hope this helps :)

Beta Mercaptoethanol disrupts the sulfide bonds of most enzymes. The portion of enzyme that withstands Beta Mercaptoethanol will bind less SDS, which ultimately leads to anomalous migration of the substrate through the electrophoresis gel.

Once the enzyme has completed its catalytic function and detached from the new molecule, it remains unchanged and can continue to catalyze other reactions. Enzymes are highly specific in their activity and can repeatedly bind to different substrate molecules to facilitate reactions without being consumed in the process.

No, not all lipids contain fatty acid chains.

Glycolipids may be involved in cells signalling that they're ''self''; to allow the immune system to recognise them.

They could also be hormone receptors

Glycolipids are a carbohydrate with lipids attached. Their main function is to provide energy and to serve as markers for cellular recognition.

Glycolipids are found in cell membrane animals tissues and nerve cells, composed of lipids and carbohydrates such as glucose or galactose as in cerebrosides or combination with sialic acids in gangliosides. It provide energy as well as cell recognition. In cell membrane it is bonding with water molecules.
