What do enzymes do inside living cells?
Enzymes are inside our cells in our body, they are meant there so we won't be sick and feel terrible, not only us but the cells protecting the enzymes are protecting us so we won't feel terrible, but it depends on how you help your body, the cells, and the enzymes.
Microbial enzymes are enzymes produced by microorganisms such as bacteria, fungi, and yeasts. These enzymes have various industrial applications in sectors like food, pharmaceuticals, detergents, and biofuels due to their specificity, efficiency, and versatility in catalyzing chemical reactions.
Effect of double bond in fatty acids to its melting point?
Fatty acids with a double bond have a lower melting point compared to saturated fatty acids with no double bonds. This is because the double bond introduces a kink in the fatty acid chain, disrupting the close packing of molecules and making it easier for them to slide past each other, resulting in a lower melting point.
Some regions of a polypeptide may coil or fold back on themselves?
Yes, certain regions of a polypeptide chain can coil or fold back on themselves due to interactions between amino acids within the chain. These interactions, such as hydrogen bonding and hydrophobic interactions, help stabilize the folded structure of the protein, ultimately determining its function.
Do chloroplasts convert sunlight into energy?
Yes, chloroplasts convert sunlight into energy through the process of photosynthesis. Light energy is absorbed by chlorophyll molecules in the chloroplasts, which then convert this energy into chemical energy in the form of glucose.
What is the main monosaccharide?
The most common monosaccharides of carbohydrates are fructose and glucose. (=sucrose)
What is the role of tRNA in translation?
tRNA is used to carry the 20 different amino acids dissolved in the cytoplasm to the ribosomes to help build the polypeptide chain for proteins to be synthesized. Each tRNA molecule attaches to one type of amino acid.
Water is a good coolant because of its hig heat of?
Water is a good coolant because of its high heat capacity, which allows it to absorb and transfer large amounts of heat without significant temperature change. This property makes it effective at regulating temperature in various systems, such as engines or industrial processes.
What are two features of a denatured enzyme?
Two features of a denatured enzyme are loss of its three-dimensional structure and subsequent loss of its biological activity. Denaturation can be caused by factors such as high temperature or extreme pH levels, leading to irreversible changes in the enzyme's shape and function.
What type of bond joins amino acid?
A peptide bond joins amino acids together in a protein chain. This bond forms between the carboxyl group of one amino acid and the amino group of another, resulting in the release of a water molecule.
Who made the army the backbone of imperial power?
Emperor Augustus of Rome is credited with transforming the Roman army into the backbone of imperial power. He established a professional and well-trained military force that played a crucial role in expanding and maintaining the Roman Empire's territories.
In mitosis we have exact replica of cell. It means after fertilization of ovum by sperm, we get a single cell witch go on duplicating to provide entire human being. This occurs by the process of cell duplication called mitosis in all genetic material get duplicated in each cell. In meiosis, we have half of the genetic material. (Half chromosomes.) So during fertilization half chromosomes from father and half from mother unite to form what we called fertilized ovum.
What are primary standard substances?
These substances are very pure materials, having a serious quality certificate, prepared only by authorized laboratories, intended to be used as reference materials for chemical analysis, validation of analysis methods, checking of instruments, legal analysis etc.
How do you prepare 0.01M sodium borate buffer?
To prepare 0.01M sodium borate buffer, you would mix the appropriate amounts of sodium borate and water to achieve a final concentration of 0.01M. You can use a balance to measure the mass of sodium borate needed and then dissolve it in water to make the desired volume of buffer solution. Adjust the pH as necessary with a strong acid or base.
What is the purpose of a transfer RNA?
Transfer RNA (tRNA) plays a crucial role in protein synthesis by carrying specific amino acids to the ribosome during translation. Each tRNA molecule has an anticodon region that binds to the corresponding codon on messenger RNA, ensuring that the correct amino acid is added to the growing polypeptide chain.
What chemicals are released when we laugh?
When we laugh, our body releases endorphins, which are hormones that act as natural painkillers and mood boosters. Laughing also increases the release of dopamine, a neurotransmitter associated with pleasure and reward, and reduces levels of cortisol, a stress hormone. Overall, laughing has been shown to have positive effects on both our physical and mental well-being.
What would happen if the Spot of origin is lowered into the solvent in chromatography?
If the original spots were below the level of developing solvent then the components of the spotted sample would dissolve into the solvent and no spots would be seen upon analysis because all of the sample is dissolved in the developing solvent.
hope this helps. good luck in o. chem!
What does B vitamins do for your body?
B vitamins play essential roles in maintaining overall health, including promoting energy production, supporting brain function, aiding in red blood cell formation, and contributing to a healthy metabolism. They are important for converting food into energy and for supporting the nervous system.
Role of distal histidine in myoglobin?
The distal histidine in myoglobin serves as a gatekeeper that helps to control the access of ligands (such as oxygen) to the heme iron. It stabilizes the bound ligand and prevents it from oxidizing, while also facilitating ligand binding and release. Additionally, the distal histidine can influence the rate of ligand binding and dissociation through hydrogen bonding interactions.
What color tubes prevent glycolysis?
Gray tubes containing sodium fluoride and potassium oxalate are commonly used to prevent glycolysis by inhibiting the enzymes responsible for breaking down glucose in the blood sample. These additives help preserve glucose levels for accurate testing in the laboratory.
A beta barrel is a protein structure where beta strands form a cylindrical shape that typically surrounds a central pore. This structure is commonly found in transmembrane proteins that span lipid bilayers. Beta barrels play essential roles in various cellular processes, including transport of molecules across membranes and as receptors for signaling molecules.
What is an antithrombotic agent?
An antithrombotic agent is a medication that helps prevent blood clots from forming in the blood vessels. These agents are used to reduce the risk of conditions such as heart attacks, strokes, and deep vein thrombosis. Examples of antithrombotic agents include aspirin, heparin, and warfarin.
What element that makes up 65 percent of human body?
Short Answer:
Carbon provides 18 or 19 percent of the total mass of the human body.
Not as much as oxygen which makes up approximately 65% of the human body mass.
Numerically, hydrogen approaches 65% of the total number of atoms in the human body, but it is probably closer to 63% for most people.
Accounting by Mass:
The mass of the human body is provided mostly by oxygen, carbon, hydrogen, nitrogen. Together these elements account for about 96% of the mass of a human.
Add in about a kilogram of calcium in the bones and body fluids and you are up to 97.4%. All of this depends on the particular person since water, our major component, can differ by 10% from one individual to another.
That said, typically the breakdown goes like this.
Oxygen: 65% of the mass
Carbon: 18% of the mass
Hydrogen: 10% of the mass
Nitrogen: 3% of the mass
Calcium: 1.4 % of the mass
Phosphorus 1.1% of the mass
With phosphorus, one has accounted for 98.5% of the mass of the typical human and that will change by a couple of tenths from person to person.
Accounting by Numbers:
Numerically we have nearly twice as many hydrogen atoms in our bodies as compared to all other elements combined. Specifically, hydrogen counts as 63% of our atoms by number, give or take a bit, but being so light it barely gets to 10% of our mass. Oxygen atoms count as 24% and carbon atoms are a mere 12% of the populations. Together, our three basic organic building blocks account for 99% of all the atoms in the body.
Caveat:
As was said above, the water content of the human body weight varieties between 55 to 65 % from one person to the next and being the major component changes the numbers above a little for each individual.
Summary:
Almost 99% of the mass of the human body is made up of the six elements oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.
Most of the last 1% is made up of five elements: potassium, sulfur, sodium, chlorine, and magnesium, but a tenth of a percent or so is made up of another dozen or so elements which include those recognized as essential to health such as iron, iodine and fluorine as well as beneficial trace elements like manganese, copper and zinc.
