Which of the following statements about Monod's diauxic growth curve is FALSE? The bacteria prefer glucose, and only eat lactose when glucose is exhausted. The bacteria are eating both glucose and lactose in the initial phase of logarithmic growth, and they slow down in the middle of the growth curve when they run out of lactose. Lactose consumption requires expression of both a permease to allow it into the cell and a b-galactosidase to metabolize it into two monosaccharides The concentration of lactose in the culture only goes down in the middle of the diauxic curve, after all the glucose is consumed. The bacteria pause growth in the middle of the growth curve because it takes them a while to induce the genes required for lactose consumption

Acidification is achieved by an H+ pump in the endosomal membrane, which also contains Cl– channels. if the channels do not function properly (e.g., because of a mutation in the genes encoding the channel proteins), acidification is also impaired. Can you explain how Cl– channels might help acidification? According to your explanation, would the Cl– channels be absolutely required to lower the pH inside the endosome?
Amoeboid cells that migrate through our tissues, such as the class of white blood cells known as neutrophils, often do so in a directed manner, triggered, for instance, by chemical signals released by pathogens such as bacteria. Directed migration in response to a chemical stimulus is known as chemotaxis. Part of an efficient chemotactic response is the ability of cells to polarize. As is the case with our structurally-polar polymers like F-actin or microtubules, polarization here refers to an asymmetry in the cells, rather than an electrical charge. In this case, it involves one part of the cell becoming the “front” (or leading edge) and another the rear. In a well-polarized, migrating cell, it’s been observed that an active form of Rac (which, in turn, can activate ARP 2/3) is concentrated towards the front of the cell, whereas an active form of Rho (which, in turn, can activate formin, inhibit ADP, and activate myosin II) is found toward the rear of the cell. Based on your…
