Much of the energy released in catabolic reactions is captured in atp for use in other reactions. when the phosphate is transferred directly from an organic molecule to adp in order to produce atp without an energized membrane, what has occurred?
a. substrate-level phosphorylation
b. oxidative phosphorylation
c. noncyclic photophosphorylation
d. cyclic photophosphorylation

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2

What is the energy of a photon of ultraviolet radiation with a frequency of 4.4 × 1015 hz? planck’s constant is 6.63 × 10–34
