Biochemistry

Biochemistry is the study of the structure, composition and chemical processes in all living organisms. It covers the structures and functions of various cellular components, including proteins, carbohydrates, nucleic acids, lipids, and other biomolecules.

How is glucose changed during glycolysis what products are produced as a result of glycolysis?

Glycolysis is the process during which glucose is broken in half, and produces pyruvic acid (3-carbon compound)

What are differences between isolation and purification?

Isolation involves separating a specific target compound from a mixture, while purification involves removing impurities from a compound to obtain a pure substance. Isolation focuses on obtaining the target compound in its natural form, while purification aims to remove any contaminants or unwanted substances from the compound.

What form do proteins need to be in to go through the electron transport chain?

Proteins need to be in the form of enzymes embedded in the inner mitochondrial membrane to participate in the electron transport chain. These enzymes facilitate the transfer of electrons from one molecule to another, generating a proton gradient used to produce ATP.

Why is it that nitric acid is used in gmelin's test?

Nitric acid is used in Gmelin's test to detect the presence of manganese in a sample. The reaction involves the formation of a green precipitate of manganese dioxide, which indicates the presence of manganese.

What mechanism is used to finely tune enzyme activity according to the needs of the cel l?

Allosteric regulation is a mechanism commonly used to finely tune enzyme activity. This involves the binding of a molecule at a site other than the active site, leading to a change in enzyme conformation and subsequent modulation of its activity. By responding to changes in the cellular environment, enzymes can maintain proper levels of activity to meet the cell's metabolic demands.

What plant uses the most magnesium?

Plants that use the most magnesium include those that are heavy feeders, such as tomatoes, peppers, and potatoes. Magnesium is essential for photosynthesis and overall plant growth, so these types of plants require higher levels of magnesium to thrive.

Where are Hormones held before released?

Hormones are produced and stored in endocrine glands before being released into the bloodstream. These glands include the pituitary gland, thyroid gland, adrenal gland, pancreas, and ovaries/testes. Hormones are released in response to specific signals to regulate various functions in the body.

What would be the likely outcome if you increased the concentration of substrate for an enzyme in the presence of a noncompetitive inhibitor?

Increasing the concentration of substrate will not overcome the effect of a noncompetitive inhibitor. The inhibitor binds to the enzyme at a site other than the active site, causing a conformational change that reduces the enzyme's activity. Therefore, increasing the concentration of substrate will not result in a significant increase in enzyme activity.

What is a living thing that grows in the earth?

A plant is a living thing that grows in the earth. Plants draw nutrients from the soil, sunlight, and water to undergo photosynthesis and grow.

When a second EPSP arrives at a single synapse before the effect of the first have disappeared what occurs?

The two EPSPs summate, leading to a higher membrane potential change and increasing the likelihood of an action potential being generated in the postsynaptic neuron. This phenomenon is known as temporal summation.

Does a B complex vitamin contain all of the B vitamins?

It usually contains only the main vitamins of the B Complex, except on medicines with a complete formulation thus containing all the vitamins and minerals as well.

What are three cattle breeds?

Angus, Hereford, and Holstein are three popular cattle breeds known for their meat and dairy production capabilities. These breeds are widely used in the agricultural industry for beef and milk production.

Which reaction is uphill anabolic or catabolic?

Anabolic reactions are typically uphill reactions because they require energy input to build complex molecules from simpler ones. On the other hand, catabolic reactions are typically downhill reactions because they break down complex molecules into simpler ones, releasing energy in the process.

What is permeadility?

Permeability is a measure of how easily fluids can flow through a porous material such as soil or rock. It is a property that affects the movement of fluids like water and gases through the material. Materials with high permeability allow fluids to flow through them easily, while materials with low permeability restrict fluid flow.

Does chemosynthesis release carbon dioxide into the atmosphere?

Taking 'chemosynthesis' to be equivalent to 'biochemistry', it occurs [in this case] in two forms: one releases CO2 and the other removes it.

A Plant in the Dark needs to respire and consume O2 and sugars to produce Atp - just the same as Animals do.

Only in the Light can a Plant or any other Photosynthetic Organism remove CO2 from the Air and release O2 instead, as found in the biochemical process called photosynthesis.

Where can I find Dog DNA testing kits?

In order for an individual to require a dog DNA testing kit, one should contact a veterinarian. There are also ways to order these kits online, but checking with your pets doctor to be on the safe side is recommended with anything that involves their health.

Why DNA isolated stored in buffer not water?

DNA is stored in buffer solution to maintain its stability and prevent degradation. The buffer helps to maintain the pH of the solution, prevent contamination, and protect the DNA from enzymatic degradation. Storing DNA in water alone can lead to degradation and loss of integrity.

How did radioactivity change or impact the scientific world?

One thing is that now the correct age of the earth could be calculated. Before radioactivity was discovered the earth was though to have cooled enough to be only about 25 million years old by calculation. The discovery of radioactivity changed all that by increasing the heat the earth could radiate and so increasing the age of the earth dramatically.

What is the effect of calcitonin and parathyroid hormone?

Calcitonin decreases blood calcium levels by promoting calcium deposition in bones, inhibiting bone breakdown and reducing calcium reabsorption in the kidneys. Parathyroid hormone increases blood calcium levels by stimulating bone breakdown, increasing calcium absorption in the intestines, and promoting calcium reabsorption in the kidneys.

Do eggs test positive in benedicts test?

Yes, eggs can test positive in the Benedict's test because they contain glucose, which is a reducing sugar that reacts with the reagent in the test to form a colored precipitate.

What is the composition a chitin?

Chitin is a polymer that is made up of a derivative of sugar, N-acetylglucoseamine. It forms the main components of cell walls of fungi, beaks of cephalopods, radula of mollusks, and the exoskeletons of insects and crustaceans.

What of the substance sucrose or water causes the formation of pollen tube?

Sucrose acts as a source of energy for the growing pollen tube, providing the necessary fuel for its elongation. Water is crucial for maintaining turgor pressure within the pollen tube, which helps it to push through the pistil tissues during growth. Both substances play essential roles in the formation and elongation of pollen tubes.

Can you add vitamins into baked goods?

maybe but it is said that vitamins will die(spilt up)if they are heated too much.i dont think oven is cool enough for them to survive but you may have a try since there will hardly be any loss.good luck!

How many mls of a 100mmolar glycine solution contains .005 moles of glycine?

Some conversion required. (mmolar into mol, or moles into mmol )

Molarity = moles of solute/Liters of solution

100 millimolar = 0.1 M glycine

Molarity = moles of solute/Liters of solution

manipulate algebraically

Liters of solution = moles of solute/Molarity

0.005 mole glycine/0.1 M glycine

= 0.05 Liters ( 1000 ml/1 L)

= 50 milliliters of solution

What is Aluminum Subacetate Solution?

Aluminum subacetate solution is a topical astringent that is used to help relieve itching, stinging, and skin irritation. It works by constricting blood vessels and reducing inflammation in the skin. It is commonly used to treat minor skin conditions such as insect bites, rashes, and minor cuts.
