What happens during Anaphase B?
A. The APC/C gets activated for the first time. B. The spindle apparatus disassembles. C. Kinetochores are pulled toward the poles. D. The nuclear envelope reforms. E. The spindle poles move apart.
Phosphofructokinase is regulated by a number of factors, including high levels of ATP. Why is this enzyme regulated by ATP levels?
A. If ATP levels are high, this provides a mechanism to directly inhibit the electron transport chain, thus preventing the formation of a proton gradient in the intermembrane space of mitochondria. B. If ATP levels are high, this provides a mechanism to directly inhibit the Krebs cycle, thus preventing further generation of NADH, FADH2, and ATP molecules that are not needed. C. If ATP levels are high, it is important to directly inhibit the reaction that commits the substrate to glycolysis to allow the substrate to be available for other reactions, since the cell has ample energy. D. If ATP levels are high, it is important to inhibit ATP synthase, and phosphofructokinase directly inhibits ATP synthase.
Why do most of the flowers in a temperate deciduous forest bloom in the spring?
A) The leaves of deciduous trees do not block the light in the spring; therefore, sunlight reaches the forest floor. B) The largest number of insect pollinators is available in the spring. C) In the spring, the trees do not block the wind and thus do not prevent wind pollination. D) The spring is the dry season; most of the rain falls during the cool, wet winters. E) Nutrients are most available in the spring.
