Who descoverd cell and how |
|
Answer» l was FIRST discovered by Robert Hooke in 1665, which can be found to be described in his book Micrographia. In this book, he gave 60 ‘observations’ in detail of various objects under a coarse, compound microscope.One observation was from very thin slices of bottle cork. Hooke discovered a multitude of tiny pores that he named "cells". This came from the Latin word Cella, meaning ‘a small room’ like monks lived in and also Cellulae, which meant the SIX sided cell of a honeycomb. HOWEVER, Hooke did not know their real structure or function. What Hooke had THOUGHT were cells, were actually empty cell walls of plant tissues. With microscopes during this time having a low magnification, Hooke was unable to see that there were other internal components to the cells he was observing. Therefore, he did not think the "cellulae" were alive. His cell observations gave no indication of the nucleus and other organelles found in most living cells. In Micrographia, Hooke also observed mould, bluish in color, found on LEATHER. After studying it under his microscope, he was unable to observe “seeds” that would have indicated how the mould was multiplying in quantity. This led to Hooke suggesting that spontaneous generation, from either natural or artificial heat, was the cause. Since this was an old Aristotelian theory still accepted at the time, others did not reject it and was not disproved until Leeuwenhoek later discovered that generation was achieved otherwise. |

1. We should always breathe through our nose- |
|
Answer» tion:Because the nostrils are smaller than the mouth, air EXHALED through the NOSE creates a back flow of air (and oxygen) into the LUNGS. And because we exhale more SLOWLY through the nose than we do though the mouth, the lungs have more time to extract oxygen from the air we've ALREADY taken in. |

Prove enzymes are substrate specific with the help of different enzymes? |
|
Answer» The enzyme ‘s active site binds to the substrate.Increasing the temperature generally increases the rate of a reaction, but dramatic changes in temperature and pH can denature an enzyme, thereby abolishing its action as a catalyst.The induced fit model states an substrate binds to an active site and both change shape slightly, creating an ideal fit for catalysis.When an enzyme binds its substrate it FORMS an enzyme-substrate complex.Enzymes promote chemical reactions by bringing substrates together in an optimal orientation, thus creating an ideal chemical environment for the reaction to occur.The enzyme will ALWAYS return to its original state at the completion of the reaction.Key Termssubstrate: A reactant in a chemical reaction is called a substrate when acted upon by an enzyme.induced fit: Proposes that the initial interaction between enzyme and substrate is relatively WEAK, but that these weak interactions rapidly induce conformational changes in the enzyme that strengthen binding.active site: The active site is the part of an enzyme to which substrates bind and where a reaction is catalyzed.Enzyme Active Site and Substrate SpecificityEnzymes bind with chemical reactants called substrates. There may be ONE or more substrates for each type of enzyme, depending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products. In others, two substrates may come together to create one larger molecule. Two reactants might also enter a reaction, both become modified, and leave the reaction as two products.The enzyme’s active site binds to the substrate. Since enzymes are proteins, this site is composed of a unique combination of amino acid residues (side chains or R groups). Each amino acid RESIDUE can be large or small; weakly acidic or basic; hydrophilic or hydrophobic; and positively-charged, negatively-charged, or neutral. The positions, sequences, structures, and properties of these residues create a very specific chemical environment within the active site. A specific chemical substrate matches this site like a jigsaw puzzle piece and makes the enzyme specific to its substrate.Active Sites and Environmental ConditionsEnvironmental conditions can affect an enzyme’s active site and, therefore, the rate at which a chemical reaction can proceed. Increasing the environmental temperature generally increases reaction rates because the molecules are moving more quickly and are more likely to come into contact with each other.However, increasing or decreasing the temperature outside of an optimal range can affect chemical bonds within the enzyme and change its shape. If the enzyme changes shape, the active site may no longer bind to the appropriate substrate and the rate of reaction will decrease. Dramatic changes to the temperature and pH will eventually cause enzymes to denature.Induced Fit and Enzyme FunctionFor many years, scientists thought that enzyme-substrate binding took place in a simple “lock-and-key” fashion. This model asserted that the enzyme and substrate fit together perfectly in one instantaneous step. However, current research supports a more refined view called induced fit. As the enzyme and substrate come together, their interaction causes a mild shift in the enzyme’s structure that confirms an ideal binding arrangement between the enzyme and the substrate. This dynamic binding maximizes the enzyme’s ability to catalyze its reaction.imageFigure: Induced Fit: According to the induced fit model, both enzyme and substrate undergo dynamic conformational changes upon binding. The enzyme contorts the substrate into its transition state, thereby increasing the rate of the reaction.Enzyme-Substrate ComplexWhen an enzyme binds its substrate, it forms an enzyme-substrate complex. This complex lowers the activation energy of the reaction and promotes its rapid progression by providing certain ions or chemical groups that actually form covalent bonds with molecules as a necessary step of the reaction process. Enzymes also promote chemical reactions by bringing substrates together in an optimal orientation, lining up the atoms and bonds of one molecule with the atoms and bonds of the other molecule. This can contort the substrate molecules and facilitate bond-breaking. The active site of an enzyme also creates an ideal environment, such as a slightly acidic or non-polar environment, for the reaction to occur. The enzyme will always return to its original state at the completion of the reaction. One of the important properties of enzymes is that they remain ultimately unchanged by the reactions they catalyze. After an enzyme is done catalyzing a reaction, it rele |

Answer» oing to my FRIEND's birthday party. Suddenly, the light went out. After a minute or two, the light CAME back. And all my friend's gifts were gone. But there was a small piece of paper and out was blank. Then I remembered something my science teacher taught me, "When you see a blank piece of paper, PUT it against something warm. Then sometimes something will be shown. That is lemon. And it has been heated." So I put it against the light bulb and something WRITTEN popped up. It said "Go to the BACKYARD". |

Answer» already used the COG approach to demonstrate the complementarity of the phyletic patterns of the three forms of phosphoglycerate mutase (SEE 2.2.6). Figure 7.1 shows the COGs that are known or predicted to include glycolytic enzymes and shows their phyletic patterns. This SUPERPOSITION of COGs and metabolic pathways provides a convenient framework for a detailed analysis of the phylogenetic distribution of each of the glycolytic enzymes and the general principles of evolution of carbohydrate metabolism. This figure shows, for example, that R. prowazekii, an obligate intracellular parasite and a relative of the mitochondria [30], does not encode a single glycolytic enzyme. In CONTRAST, all other organisms with completely sequenced genomes encode enzymes of the lower (tri-carbon) part of the pathway. This supports the notion that glycolysis is the central pathway of carbohydrate metabolism and makes comparative analysis of VARIANTS of this pathway all the more interesting. |
