50 is B
51 is F
52 is D
and 53 is E
Explanation:
it fits the most that way
Answer:
b. Because they have a low affinity for the H+
Explanation:
All electrons that enter the transport chain come from NADH and FADH2 molecules that are produced in earlier phases of cellular respiration: glycolysis, pyruvate oxidation and the citric acid cycle.
NADH is very good at donating electrons in redox reactions (that is, its electrons are at a high energy level), so you can transfer your electrons directly to complex I and transform it back into NAD +. The movement of electrons through complex I in a series of redox reactions releases energy, which the complex uses to pump protons from the matrix into the intermembrane space.
FADH2 is not as good for donating electrons as NADH (that is, its electrons are at a lower energy level), so it cannot transfer its electrons to complex I. Instead, it introduces electrons to the transport chain through complex II, which does not pump protons through the membrane.
This happens because the muscle cells respire anaerobically and the glucose is not broken down completely, and Lactic acid is formed. The lactic acid causes pain in the muscles.
Answer:
Most migration abilities are learned responses. The delicate balance of life within a biome can be disturbed by people's lack of knowledge. A danger signal sent by nerves is often felt as pain.
