Question: Answer the following question given this paragraph: Pyruvate still contains a great deal of chemical energy. In fact, two pyruvate molecules contain most of the chemical energy from the original glucose molecule. If oxygen is present, pyruvate enters the mitochondria for complete breakdown by the Krebs Cycle and electron transport chain. If oxygen is not present, cells must transform pyruvate to regenerate NAD + in order to continue making ATP. Keep in mind that glycolysis produces a net total of 2 ATP. Q: What kind of energy does pyruvate have a lot of? Choices: - thermal - nuclear - gravitational - chemical A:
Answer: chemical

Answer the following question given this paragraph: For example, your body has an internal thermostat. During a winter day, in your house a thermostat senses the temperature in a room and responds by turning on or off the heater. Your body acts in much the same way. When body temperature rises, receptors in the skin and the brain sense the temperature change. The temperature change triggers a command from the brain. This command can cause several responses. If you are too hot, the skin makes sweat and blood vessels near the skin surface dilate. This response helps decrease body temperature. Q: Like a house, your body has what kind of mechanism that responds to changes in temperature? Choices: - external thermostat - mechanical thermostat - sensitive thermostat - internal thermostat A:
**Answer**
internal thermostat
