Which of the following statements about feedback regulation of a metabolic pathway is incorrect? 1) the final product of a metabolic pathway is the compound that regulates the pathway 2) the products of the pathway become the reactants for a different reaction, and thus products are unable to accumulate. 3) the enzyme that is regulated by feedback inhibition is usually the first enzyme in the metabolic pathway 4) the compound that regulates the pathway acts as a non-competitive inhibitor or a negative allosteric regulator. 5) accumulation of the product of the pathway will tend to slow down further formation of that product

You have been asked to lead a demonstration for the undergraduate microbiology lab course about the uses of negative staining when studying bacteria. a "negative" stain does not stain the bacterial cell itself but stains the space between cells. under magnification, the acidic (negativelycharged) nature of the stain will be repelled by the negatively charged bacterial cell wall and willleave the cell colorless in a stained background. negative stains are used primarily to reveal the presence of negatively charged bacterial capsules; therefore, they are also called capsule stains. encapsulated cells appear to have a halo surrounding them. the negative stain procedure does not require heat fixation, which limits any chances of alteration in bacterial cell shape and size. the bacterial suspension is added to a drop of stain, such as nigrosin or eosin, and drawn across the glass slide using a coverslip.nigrosin staining-not safranin staining-of klebsiella pneumoniae will allow for the visualization of the cell shape and the determination of the presence of a capsule.true/false
