Answer:
endothermic
Explanation:
A reaction in which energy is absorbed from the surroundings is called an endothermic reaction. In endothermic reactions the enthalpy of the products is greater than the enthalpy of the reactants. Because reactions release or absorb energy, they affect the temperature of their surroundings.
Answer: Succinate dehydrogenase
Explanation: succinate dehydrogenase or Complex II or succinate-coenzyme Q reductase is an enzyme complex involved in citric acidic cycle, bound to the inner mitochondrial membrane of mammalian mitochondria and cell membrane of many bacterial cells. It is the only enzyme that participates in both the citric acid cycle and the electron transport chain. This enzyme catalyzes the oxidation of succinate to fumarate with the reduction of ubiquinone to ubiquinol, reaction occurs in the inner mitochondrial membrane by coupling the two reactions together.
<span>The globin chains of myoglobin and hemoglobin prevent the oxidation of Fe2 to Fe3 , which irreversibly binds oxygen. The cooperativity of oxygen binding in hemoglobin arises from electronic interactions between heme groups.</span>
Answer:
Duplication is a type of mutation that involves the production of one or more copies of a gene or region of a chromosome. Gene and chromosome duplications occur in all organisms, though they are especially prominent among plants. Gene duplication is an important mechanism by which evolution occurs.
