Biochemistry

Homo = same, homogenous.

Hetero = different.

So, the homopolysaccharide is made of of many of the same sugars in it's chain.

While the heteropolysaccahride is made of of different type sugars in ot's chain.

KOH will dissolve into K+ and OH-, which would make K+ cations available for uptake by a plant for instance. However, KOH is a strong base (dissociates nearly 100% into ions) and thus will significantly increase the pH of your watering solution, possibly beyond levels your plant can tolerate...NOT RECOMMENDED!

The optimum temperature for enzyme activity in the body is typically around 37°C (98.6°F), which is body temperature. Enzymes function best within a narrow temperature range, and deviations from this temperature can result in decreased enzyme efficiency or denaturation.

Guanine (G) and Cytosine (C) are joined together with three hydrogen bonds, whereas Adenine (A) and Thymine (T) are only held together with two.

This makes G and C more stable than A and T.

Low levels of vitamin D have been associated with an increased risk of developing certain types of cancer, including breast, prostate, colorectal, and pancreatic cancer. However, vitamin D deficiency alone is not the direct cause of cancer; rather, it is one of many factors that can contribute to an individual's overall risk of developing cancer.

yes. the extent will vary with the temperature of the water

The organic solvents are either acidic or basic and capable of producing protons and ions. These protons and ions changes the pH of the solution in which they are present. Once the pH is changed the amino acids cannot retain its original form. They tend to form either cation or anion which inturn alters the normal structure of the protein (enzyme) and hence the activity is also inhibited.

It could happen in three main manners: 1) the formation of multiple copies of the gene (duplications) that increase the expression of the gene 2) the mutation happens in the promoter of the gene or in others non coding regions causing an increase in the level of the mRNA of the gene 3) it could happen a translocation that put the gene under an active promoter (bcl2 in lymphomas) , or brings to the formation of a chimaeric gene (the philadelphia chromosome in leukemia)

Fat-soluble vitamins are stored in the body's fat tissues, while water-soluble vitamins are excreted in urine when in excess since the body does not store them. This is because fat-soluble vitamins can be stored in fat cells and released when needed, while water-soluble vitamins are readily excreted when the body has enough.

Western Blots used to diagnose HIV infection detect antibody to a range of HIV proteins. Instead of giving just one answer, they show "positive" or "negative" for each protein on the western blot strip. This makes them very specific for HIV.

The number of peptide linkages in a nanopeptide will depend on the specific amino acid sequence of the peptide. Each peptide bond forms between the amino group of one amino acid and the carboxyl group of another amino acid, so the number of peptide linkages will be one less than the number of amino acids in the sequence.

Diffusion is the passive movements of particles from an area of higher concentration to an area of lower concentration.

Osmosis is the movement of water molecules across a partially permeable membrane from a region of higher water concentration to a region of lower concentration.

DNA contains the genetic instructions for building and maintaining living organisms. It is a molecule that stores genetic information, carries instructions for protein synthesis, and is involved in the regulation of gene expression. DNA ultimately determines an organism's traits and characteristics.

ATP synthase is the protein enzyme involved in chemiosmosis. It is responsible for generating ATP by facilitating the movement of protons across the inner mitochondrial membrane.

when your mom and your dad love each other alot, the limo parks in the garage and than realizes that its not in right so he must reverse and redo..he reapeats this about 3 times......than 9 months later a new limo is made

The nucleus contains thin strands of DNA known as chromatin. Chromatin is made up of DNA and proteins, and it packages the DNA to fit inside the nucleus of a cell.

Allosteric enzymes are mostly polymeric in nature i.e. they are made up of several subunits. These enzymes exhibit cooperativity i.e. binding of a ligand to the active site alters (increase or decrease) the binding affinity of the ligand on other sites. Some monomeric enzymes also exhibit cooperativity. Those monomeric enzymes which exhibit cooperativity are called mnemonical enzymes. Hexokinase D (an isoenzyme of hexokinase) is one such example.

The major cofactor formed from folate is tetrahydrofolate (THF). It plays a crucial role in transferring one-carbon units in various biochemical reactions, including nucleotide synthesis and amino acid metabolism.

Some gonadal adrenocortical hormones include testosterone, estrogen, and progesterone. These hormones are produced in the adrenal glands as well as the gonads (testes and ovaries), and they play key roles in regulating sexual development, fertility, and reproductive functions.

The only gonadal adrenocortical hormone is dehydroepiandrosterone (DHEA). DHEA is produced in both the adrenal glands and the gonads, and serves as a precursor to other sex hormones like testosterone and estrogen.

This phenomenon would be described as transcriptional repression. It involves the inhibition of transcription when a protein binds to specific regions of DNA, typically leading to a decrease in gene expression.

Water is a universal solvent, allowing it to dissolve many substances due to its polar nature. It has a high specific heat capacity, helping to regulate temperature in living organisms and environments. Water also exhibits strong cohesive and adhesive forces, enabling it to transport nutrients and waste within organisms, as well as facilitate capillary action in plants. Overall, water's unique chemical and physical properties make it essential for life on Earth.

Antidiuretic hormone (ADH) regulates fluid intake by stimulating the kidneys to reabsorb water back into the bloodstream instead of excreting it in urine. This helps to maintain proper water balance in the body by increasing water retention. When the body detects dehydration or high salt concentration in the blood, ADH is released to prevent excessive fluid loss and increase thirst sensation to encourage more fluid intake.

In cells, energy metabolism is regulated such that the rate of ATP supply pathways will balance the rate of ATP demand pathways. This regulation is done in such a way so that the ATP/ADP levels and the levels of other intermediates involved in respiratory pathways are kept with narrow ranges. This is important because even though the rate of ATP supply and demand can change by several orders of magnitude, the ATP/ADP remains almost unchanged. This is achieved by simultaneous regulation and some 'fine tuning" regulation of supply and demand pathways. For example in muscular contraction will increase the energy demand and increase in demand relative to supply will decrease the ATP/ADP ratio which can activate ATP supply pathways. This type of regulation alone is not sufficient cause as you see the ATP/ADP ratio has to decrease first before any change is made in supply pathways, and in cases where this is a large increase in ATP demand, this decrease will be substantial. So, simultaneous regulation by Ca2+ which is a signal for muscular contraction can activate both supply and demand at the same time so that little change in ATP/ADP ratio is needed and metabolic homeostasis can be achieved
