Question
Chapter 5.4, Problem 1TQ
Summary Introduction
To review:
The working of Na+/H+ antiporter to bring protons into a haloalkaliphile growing in high salt at pH 10.
Introduction:
The microbes are categorized on the basis of various environmental parameters such as temperature, pH (potential of hydrogen), pressure, and oxygen. The microbes that survive in acidic conditions are known as acidophiles while the microbes that grow in basic conditions are called alkaliphiles. Neutrophils are those that survive in neutral conditions where the pH is between 5-8.

Nutrients must diffuse through the layer in order to sustain the organisms throughout the film.

- How do cells maintain the fluidity of their membranes? If a bacterium was growing at 20°C, how would it's membrane composition change if it was suddenly moved to cultivation temperature of 30°C.? How would it's membrane composition change if it was subsequently moved to a cultivation temperature of 10°C?arrow_forwardIn conditions of dehydration, plant cells can increase their water retention by regulating the function of some or all of their aquaporins, membrane-bound protein channels that allow water to move through the cell membrane via facilitated diffusion. Which of the following describes a likely mechanism by which aquaporins can be used to regulate the movement of water across the plant cell membrane? A B с D Synthesis of additional aquaporins by the plant cell ribosomes will allow the cell to coun- teract the movement of water out of the cell. Inhibition of ATP hydrolysis will make the aquaporins unable to remove water from the cell and cause more water to remain in the cell. Inactivation of aquaporins will make water molecules unable to move across the plant cell membrane and allow more water to remain in the cell. Inhibition of the plant cell Golgi apparatus will decrease the production rate of vesicles and slow down the exocytosis of water molecules.arrow_forward1)Suppose you were culturing a population of bacteria at 37 degrees C and then reduce the temperature of the culture to 15 degree C.
