Q: Some biochemical processes happen via sequences of reactions which are called what? Read this paragraph and choose the correct option from the provided answers: Many biochemical processes occur through sequences of reactions called pathways. The total energy released by many of these pathways is much more than the energy a cell could handle if it were all released in a single step. For example, the combustion of glucose in a single step would release enough energy to kill a cell. By using a series of smaller steps that release less energy per reaction, however, the cell can extract the maximum energy from glucose without being destroyed. Referring to Equation 5.30, calculate how many grams of glucose would need to be metabolized to raise the temperature of a liver cell from an average body 3. Choices: - synthesis - mutations - metabolism - pathways A:
pathways

Q: What type of device uses electromagnetic induction to change the voltage of electric current? Read this paragraph and choose the correct option from the provided answers: An electric transformer is a device that uses electromagnetic induction to change the voltage of electric current. Electromagnetic induction is the process of generating current with a magnetic field. It occurs when a magnetic field and electric conductor, such as a coil of wire, move relative to one another. A transformer may either increase or decrease voltage. You can see the basic components of an electric transformer in the Figure below . For an animation showing how a transformer works, go to this URL: http://www. youtube. com/watch?v=VucsoEhB0NA . Choices: - radioactive transformer - hot transformer - mechanical transformer - electronic transformer A:
electronic transformer

Q: What is regulated by the reticular formation? Read this paragraph and choose the correct option from the provided answers: Wakefulness is regulated by the reticular formation, which is present in the. Choices: - awkwardness - sleepiness - anxiousness - wakefulness A:
wakefulness

Q: Enthalpy is a measure of the total energy of what kind of system? Read this paragraph and choose the correct option from the provided answers: Reactions can proceed by themselves if they are exergonic or exothermic, that is if they release energy. The associated free energy of the reaction is composed of two different thermodynamic quantities, enthalpy and entropy. Enthalpy is a measure of the total energy of a thermodynamic system. The change in enthalpy is positive in endothermic reactions, and negative in exothermic processes. Choices: - macroscopic - planetary - hypodermic - thermodynamic A:
thermodynamic
