Why is 70 percent alcohol a better disinfectant than 100 percent alcohol?

Answer»

The 100% isopropyl alcohol COAGULATES the proteins INSTANTLY by creating a proteon layer that protects the other proteins from further coagulation. Due to this microbes are not killed but becom temporarily inactive.
While 70% isopropyl alcohol solution penetrates in the cell wall at slower rate and coagulates the all protein of the cell wall and microorganism dies.
And there US ALSO mportant role of watee which denature the proteins of cell membrane and acts as a catalyst in the reaction.

Fixation of one mole of glucose require how many cycli pathway in calvin cycle

Answer»

Calvin cycle is the cycle of chemical reactions performed by plants to “fix” carbon from CO2 into three-carbon sugars.

Later, plants and animals can turn these three-carbon compounds into amino acids, nucleotides, and more complex sugars such as starches.

This process of “carbon fixation” is how most new organic matter is created. The sugars created in the Calvin cycle are also used by plants for long-term energy storage, unlike ATP which is used up quickly after it is created.

These plant sugars can also become a source of energy for animals who eat the plants, and predators who eat those herbivores.

The Calvin cycle is also sometimes referred to as the “light independent” reactions of photosynthesis, since it is not powered directly by photons from the Sun. Instead, the Calvin cycle is powered by ATP and NADPH, which are created by harnessing the energy from photons in the light-dependent reactions.

Function of the Calvin Cycle

The function of the Calvin cycle is to create three-carbon sugars, which can then be used to build other sugars such as glucose, starch, and cellulose that is used by plants as a structural BUILDING material. The Calvin cycle takes molecules of carbon straight out of the air and turns them into plant matter.

This makes the Calvin cycle vital for the existence of most ecosystems, where plants form the base of the energy pyramid. Without the Calvin cycle, plants would be unable to store energy in a form that herbivores could digest. Carnivores would subsequently not have access to energy stored in the bodies of herbivores!

The carbon backbones created in the Calvin cycle are also used by plants and animals to make proteins, nucleic acids, lipids, and all the other building blocks of life.

The Calvin cycle also regulates the levels of carbon dioxide, a greenhouse gas, in the Earth’s atmosphere. Scientists have raised concerns because, in addition to putting huge amounts of CO2 back into the air by burning coal, oil, and gasoline, humans have also cut down about half of all Earth’s FORESTS, which play an important role in removing CO2 from the air.

We will discuss how the Calvin cycle CREATES simple sugars from CO2 below.

Calvin Cycle Steps

Carbon Fixation

In carbon fixation, a CO2 molecule from the atmosphere COMBINES with a five-carbon acceptor molecule called ribulose-1,5-bisphosphate (RuBP).

The resulting six-carbon compound is then split into two molecules of the three-carbon compound, 3-phosphoglyceric acid (3-PGA).

This reaction is catalyzed by the enzyme RuBP carboxylase/oxygenase, also known as RuBisCO. Due to the key role it plays in photosynthesis, RuBisCo is probably the most abundant enzyme on Earth.

Reduction

In the second stage of the Calvin cycle, the 3-PGA molecules created through carbon fixation are converted into molecules of a simple sugar – glyceraldehyde-3 phosphate (G3P).

This stage uses energy from ATP and NADPH created in the light-dependent reactions of photosynthesis. In this way, the Calvin cycle becomes the way in which plants convert energy from sunlight into long-term storage molecules, such as sugars. The energy from the ATP and NADPH is transferred to the sugars.

This step is called “reduction” because NADPH donates electrons to the 3-phosphoglyceric acid molecules to create glyceraldehyde-3 phosphate. In chemistry, the process of DONATING electrons is called “reduction,” while the process of taking electrons

Effect of metformin on acute promyelocytic leukemia cell line nb4 and its mechanism

Answer»

The purpose of this study was to investigate the effect and molecular mechanism of metformin (Met) on biological characteristics of ACUTE promyelocytic leukemia (APL) cell line NB4. NB4 cells were treated with various concentrations of Met for different time, MTT method was used to detect cell PROLIFERATION, the alteration of cell apoptosis was analyzed by flow cytometry, and the change of cell adhesion ability was examined by cell adhesion assay. NB4 cells were PRETREATED with U0126, a specific INHIBITOR for extracellular signal-regulated kinase (ERK) phosphorylation, ERK phosphorylation was assessed by Western blot analysis, apoptosis and cell adhesion ability were evaluated by flow cytometry and cell adhesion test respectively. The results showed that Met could inhibit the cell proliferation, induce the cell apoptosis and increase the ability of cell adhesion. The pretreatment of NB4 cells with 5 µmol/L U0126 could effectively inhibit the phosphorylation of ERK, and reduce cell apoptosis and adhesion induced by 5 mmol/L Met. It is concluded that Met can inhibit the proliferation and promote the apoptosis and adhesion of NB4 cells. MEK/ERK signaling pathway MAY be one of the molecular mechanisms of metformin on NB4 cells.

Down syndrome is a genetic disorder caused by the presence of an extra chromosome in the body cells

Answer»

There can be impairments in cognitive ABILITY and physical growth, mild to moderate developmental disabilities, and a higher risk of some health problems.

Through a SERIES of screenings and tests, Down syndrome can be detected before or after birth.

The likelihood having Down syndrome is around 1 in every 700 pregnancies. It is determined by many factors, but research suggests there is a higher risk if the mother delivers at over 35 years of age.

Before the age of 30 years, fewer than one in 1,000 pregnancies will be affected by Down syndrome. After the age of 40 years, this figure rises to about 12 in 1,000.

Down syndrome is a genetic condition that RESULTS when there is an extra copy of a SPECIFIC chromosome, chromosome 21.

It is not an illness but a term that describes the features resulting from this change.

The extra chromosome can affect the physical features, intellect, and overall development of an individual.

It also increases the likelihood of some health problems.
