Question 30 (1 point) Match these ADP Isocitrate dehydrogenase Acetyl CoA ATP Phosphofructokinase 1. Control enzyme for glycolysis 2. Control enzyme for citric acid cycle 3. Inhibits phosphofructokinase and isocitrate dehydrogenase (We've got enough already) 4. Activates phosphofructokinase and isocitrate dehydrogenase (Help! We need energy!) 5. If citric acid cycle shut down, this can become fatty acids
A rocket with mass 7.00×103 kgkg is in a circular orbit of radius 7.30×106 mm around the earth. The rocket's engines fire for a period of time to increase that radius to 8.80×106 mm, with the orbit again circular. Part A What is the change in the rocket's kinetic energy? Does the kinetic energy increase or decrease? Express your answer with the appropriate units. Enter positive value if the kinetic energy increases and negative value if the kinetic energy decreases.
