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.

Can you show Question paper bsc 4Th sem PTU?
yes i show question paper from bsc it 4h sem.
bcoz my exam is started ij march but my revision is a little bit so please show me a question paper
If iodine can move through a plastic bag why can't you breathe through a plastic bag?
Iodine molecules are much smaller than oxygen molecules, so they can pass through small openings in the plastic bag. However, the plastic bag is impermeable to air, so you cannot get enough oxygen by breathing through it. This can lead to a lack of oxygen and potentially suffocation.
What percentage of DNA do you share with dogs?
Humans and dogs only share about 25% of the exact same DNA or genome sequence. They also have a different number of chromosomes. Humans have 23 pairs of chromosomes and dogs have 39 pairs.
carotene is a substance available in cow's milk ,responsible for yellowish milk fat
What is an example of hydrophobicity?
In terms of biochemistry, hydrophobia is the repulsion shown by a molecule to water. Lipids such as glycerol are a classic example, which is not soluble in water and will float on the surface.
Do rewards make student work harder?
yes if kids get rewards they will work harder and try to get more rewards
Rickets.
This is a deficiency disease that is now recurring in England, partly due to over zealous health warnings from the government. They have talked about the dangers of the sun and skin cancer for so long that the idea that a reasonable and balanced amount of sunshine is necessary for good health has been lost.
Medical advice is like many other things - moderation in all things is good advice.
How IGM in baby's blood indicates recent infections?
The presence of IgM antibodies indicate acute infection, mostly from Parvovirus and Rubella in babies.
Conjugated enzymes are enzymes that require a non-protein component, such as a metal ion or a coenzyme, to function properly. These additional components are necessary for the enzyme to catalyze a specific reaction effectively.
The formation of a disaccharide from two monosaccharides is a reaction called?
Well according to my calculations the cause of this relates to the thermodynamic equilibrium causes the equation e=mc2 which makes the apple juice turn green. this can just plain out be a trick question. if you really think about when the apple juice turns green the apple will make 3=d=4=gh+r-77=gh its all about the way your mind thinks. take smoothie for example now you have the answer to this very simple question. oh and by the way if you read this you just let me waste a min of your life.
After the study in abroad can you get citizenship in that country?
Immigration Laws vary.Studying in a particular Country could add points if you wish to Immigrate. Using that point system you can immigrate , become a Permanent Resident of that country and then eventually a Citizen.
I suppose that you think to tobacco mosaic virus, but the chemical name is longer.
See the link below.
Large molecules may have reaction sites termed -----because they are attracted to water?
Hydrophilic sites. These sites are attracted to water molecules due to their polarity and can interact with the surrounding water molecules.
An apple shaped fat pattern increases a persons risk for?
Cardiovascular disease due to increased fat storage in the body.
It deals with the structures and functions of cellular components such as proteins, carbohydrates, lipids, nucleic acids and other biomolecules. It explains the living processes that now almost all areas of the life sciences from botany to medicine are engaged in biochemical research. Today the main focus of pure biochemistry is in understanding how biological molecules give rise to the processes that occur within living cells which in turn relates greatly to the study and understanding of whole organisms.
What makes Dna strands unique to every organism?
Their unique SEQUENCE of nucleotide BASES accomplishes this Functional Property in Dna strands.
How does enzymes speed up chemical reactions?
The way enzymes speed up chemical/biochemical reactions is the same way that catalysts work. They provide an alternate pathway for the reaction which has a LOWER activation energy. They don't actually decrease the activation energy of the pathway in question, but rather they provide a different pathway that has a lower energy of activation.
What enzyme regulates glycogenolysis?
Actually, three are the enzymes that intervene during glycogen breakdown (glycogenolysis).
- First, Glycogen phosphorylase (or simply phosphorylase) that catalyzes glycogen phosphorolysis (bond cleavage by the substitution of a phosphate group) to yield glucose-1-phosphate (G1P) releasing only one glucose residue that is at least five residues from a ramification point.
- The second enzyme is the Glycogen debranching enzymethat removes glycogen's branches, thereby permiting the glycogen phosphorylase reaction (see above) to go to completion. This enzymes also hydrolyzes alpha(1-6)-linked glucosyl units to yield glucose.
- Finally, Phosphoglucomutase that converts G1P to G6P which is also formed in the first step of glycolysis through the action of either hexokinase or glucokinase.
Think of the palmitic acid as a snickers bar. If your splitting the candy bar among eight friends you only have to cut the candy bar seven times. The concept is the same for spliting the long palmitic acid into eight acetyl-CoA's, you only have to cut it seven times in order to end with eight pieces.
