Unformatted text preview: ow does the exchange of triose- phosphate for inorganic phosphate permit this transport to occur by facilitated diffusion only? (2 points) DHAP is synthesized in the chloroplast while Pi is release in the cytosol, hence the concentration gradient drives transport. By exchanging –vely charged DHAP for –vely charged phosphate the generation of a electrochemical gradient is prevented. ii. Why is the exchange of triose- phosphate for inorganic phosphate essential for the continued operation of the reductive pentose phosphate pathway? (2 points) Without the re- import of phosphate into the chloroplast, phosphte will become depleted preventing the regeneration of ATP and triose- phosphates which are required to allow the reductive pentose phosphate pathway to proceed. [4] The following questions refer to metabolic regulation. (a) Metabolism is regulated to maintain homeostasis. Define homeostasis as it applies to metabolism. How is this different to equilibrium? (3 points) Homeostasis is the regulation of metabolism to maintain constant levels of metabolic intermediates...

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
