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.

What organelle does photosynthesis and cellular respiration occur in?
Respiration occurs in two compartments - glycolysis in the cytoplasm and the TCA cycle and electron transport chain in the mitochondria. However, cells that are actively photosynthesising do not need to respire because ATP is synthesised in the chloroplast.
The gel electrophoresis technique is developed by Joe Sambrook and Bill Sugden. They used agarose gel electrophoresis to separate DNA fragements. The most easily way the macromolecules through the gel porous starts with smallar molecules than larger molecules.
Why does the can of dust off get cold?
Joule-Thomson effect
Also known as the Joule-Kelvin effect. When a Gas expands through a porous plug, a change of temperature occurs, proportional to the pressure difference across the plug. The temperature change is due to a departure of the gas from Joule's Law, the gas performing internal work in overcoming the mutual attractions of the Molecules and thus cooling itself; and partly to deviation of the gas from Boyles law. The latter effect can give rise to either to cooling or heating, depending upon the initial temperature and pressure difference used. For a given mean pressure, the temperature at which the two effects balance, resulting in no alteration of temperature, is called the inversion temperature. Gases expanding through a porous plug below their inversion temperature are cooled, otherwise they are heated.
What do catalysts and enzymes have in common?
Here is one of those Short yet Sharp Answers: While all Enzymes are Catalysts not all Catalysts are Enzymes.
What they do share is 'the ability to be a catalyst for a chemical reaction'. Enzymes happen to specialize in Biochemical reactions.
What is trna and what does it function?
tRNAs are small RNA molecules that carry amino acids to growing polypeptide chains that are being made in a ribosome. The have anti-codons that are complimentary to the codons on the mRNA. They carry an amino acid that is specific to their anti-codon.
What is the relationship of chemistry in other sciences or fields?
In ancient times, there was no distinction of biology and other sciences. Different fields of sciences like biology, chemistry, physics and mathematics are met together in the writings of ancient scientists. In ancient times, these subjects were studied under one head "science", but with the passage of time, the science developed very much and the huge scientific knowledge was then divided into different branches.
However even today the interrelationship of these branches cannot be denied.
BiophysicsThe study of various biological phenomena according to principles of physics is called biophysics. For example, movement of muscles and bones based on principles of physics.
BiochemistryThe study of different biochemical like carbohydrates, proteins and nucleic acids etc found in cells of living organisms and hundreds of the underlying chemical reactions in cells of organisms is called biochemistry.
BiometryThe data obtained from observations and experiments on living organism is analyzed by various statistical methods. This is called Biometry.
BiogeographyThe study of plants and animals and the basis of geographical distribution is called Biogeography.
Bio-EconomicsThe study of living organisms from economic point of view is called Bio-Economics. It includes the study of cost effectiveness and viability of biological projects from commercial point of view.
Why is citric acid soluble in water?
First get a cup then go to a small dark corner and take a dump in it.
second... eat it.
now you are ready to put citric acid in water
If you cant do this, you are a complete retard.
What are some functions of enzymes in the body?
Enzymes in the body play a critical role in speeding up chemical reactions, breaking down food into nutrients for absorption, facilitating the production of energy, and regulating various metabolic processes. Enzymes also help in DNA replication, repair, and transcription, as well as in the immune system's response to pathogens.
What does cellular respiration remove from the air?
Cellular respiration removes oxygen from the air and releases carbon dioxide as a waste product.
What is the ribosomes functions?
Protein synthesis is the process done by ribosomes. Ribosomes provide surface to synthesis.
Protein synthesis is the process done by ribosomes. Ribosomes provide surface to synthesis.
What 2 macromolecules store energy in carbon hydrogen bonds?
Hydrogen bonding found in macromolecules in living things (from the most to the least):
- DNA
- proteins
- cellulose (plants)
- urea
- ammonia
The reaction in which water molecules produce ions is called?
The reaction in which water molecules produce ions is called dissociation. This process involves water molecules breaking apart into hydrogen (H+) and hydroxide (OH-) ions.
What is the definition of phosphorylation?
The addition of a phosphate group to an organic molecule. Phosphorylation is important for many processes in living cells. ATP is formed during cell respiration from ADP by phosphorylation, as in the mitochondria of eukaryotic cells (oxidative phosphorylation) and the chloroplasts of plant cells (photosynthetic phosphorylation). Phosphorylation also regulates the activity of proteins, such as enzymes, which are often activated by the addition of a phosphate group and deactivated by its removal (called dephosphorylation).

What part of the cell contains DNA apart from the nucleus?
The mitochondria contain their own DNA in plants and animals; and chloroplasts contain their own DNA in plants and other photosynthetic organisms. Both of these structures divide (almost like cells) inside the cells.
*This is also evidence for the theory of endosymbiosis, in which early cells ate early prokarotic cells (bacteria) and gained new organelles.
What is difference between suspended solid and turbidity?
Suspended solids are particles present in water that can settle out over time, while turbidity is a measure of the cloudiness or haziness of water due to particles in suspension. Suspended solids are the actual particles in the water, while turbidity is a measure of how those particles affect the clarity of the water.
What 3 cycles are involved in cellular respiration?
1. glycolysis
2. transition stage
3. the kreb cycle
4. the electron transport chain
Is OH Polar or Non- polar covalent?
The O-H bond is polar covalent. Very strongly polar because of the difference in electronegativity.
What functional group is in lysine?
The functional group in lysine is an amino group (-NH2) which is part of its side chain.
DCPIP (2,6-dichlorophenolindophenol) is a chemical compound commonly used as an indicator in biochemical assays. It is blue when oxidized and colorless when reduced. DCPIP is often used to measure the presence of vitamin C in various solutions.
