Answer:
DNP produces the loss of the proton gradient (i.e., the energy of the proton gradient is dissipated in the form of heat instead to produce ATP)
Explanation:
2,4-Dinitrophenol (DNP) acts to shuttle H+ ions across cellular membranes, bypassing the ATP synthase used by mitochondria to generate ATP during cellular respiration. Since DNP is able to bypass ATP synthase, this compound uncouples the phosphorylation of ADP by the ATP synthase from the process of oxidation (i.e., transport of electrons). For example, in muscle cells, DNP may be used to shuttle calcium ions (Ca +) from mitochondrial stores, and free intracellular Ca+ ions are evidenced to produce muscle contraction.
Answer:
there is no picture try asking a question again :)
Explanation:
Answer: B. The distribution of some groups of ostrich like birds may have been influenced by continental drift in what is known as Pangea.
Explanation:
Answer:
The statement that is false is <u>metabolism is regulated largely by the nervous system.</u>
Explanation:
The metabolism reactions are controlled by the enzymes specific for each metabolic reactions. After a signal is generated, specific enzymes that detect the signal starts up the metabolic reactions.
When there is a need to stop a certain metabolic reaction, then the mechanism of feedback inhibition is used which stops the enzyme from carrying out any further reactions. Hence, the statement that metabolism is regulated largely by the nervous system is false.
