Effect of Rotenone and Antimycin A on Electron Transfer Roteno
Question

Question asked by Filo student

Effect of Rotenone and Antimycin A on Electron Transfer Rotenone, a toxic natural product from plants, strongly inhibits NADH dehydrogenase of insect and fish mitochondria. Antimycin a toxic antibiotic, strongly inhibits the oxidation of ubiquinol.(a) Explain why rotenone ingestion is lethal to some insect and fish species.(b) Explain why antimycin A is a poison.(c) Given that rotenone and antimycin A are equally effective in blocking their respective sites in the electrontransfer chain, which would be a more potent poison? Explain.

The given diagram shows axon terminal. Select the option that correctly matches the steps in transmission of impulses (list i - vii) with the labeling (A-D) in diagram.

(i) Chemicals called neurotransmitters are released in the synaptic cleft through ion channels.
(ii) When an impulse arrives at the axon terminal, it stimulates the movement of synaptic vesicles.
(iii) Neurotransmitters are endocytosed into the neurons.
(iv) The ion channels close with the binding of neurotransmitters to their specific receptors vesicles.
(v) Synaptic vesicles move towards the membrane where they fuse with the plasma membrane.
(vi) Neurotransmitters are released in the synaptic cleft.
(vii) The released transmitters bind to their specific receptors on postsynaptic membrane.

What are the key traits of Homo sapiens that make us "human"? Which hominin species from the genus Homo first qualifies as "human"? Homo erectus vs Homo sapiens (us). Are the traits identical? How do they differ? Does this difference show the species as "human" or not? Are they enough like us that you consider them "human" or "people"? Compare each. Shape and function of the pelvis, legs, and feet for bipedal walking. Body proportions related to adaptations for temperature and climate. Size and shape of the jaw and teeth as they relate to diet.
