Why do we have different time zones
swat32

As Earth rotates, different parts of Earth receive sunlight or darkness, giving us day and night. Since different parts of Earth enter and exit daylight at different times, we need different time zones. In the late 1800s, a group of scientists figured out a way to divide the world into different time zones.

Which of the following is correct? Which of the following is correct? Most of the ATP are produced by substrate-level phosphoryl
Nezavi [6.7K]

Answer:

Each FADH2 yields about 1.5 ATP via oxidative phosphorylation.

Explanation:

Most of the ATP molecules are produced by oxidative phosphorylation, not by substrate-level phosphorylation. During glycolysis, 2 ATP molecules per glucose are produced by substrate-level phosphorylation. Similarly, Kreb's cycle also yields 2 ATP per glucose by substrate-level phosphorylation.

For each pair of electrons transferred to O2 from FADH2 via electron transport chain, 4 and 2 protons are pumped from matrix towards the intermembrane space by complex III and complex IV respectively. It generates the proton concentration gradient required to drive the synthesis of 1.5 ATP molecules. Since oxidation of FADH2 is coupled to the phosphorylation of ADP to form ATP, the process is called oxidative phosphorylation.

A nurse is caring for a client with varicose veins. which clinical manifestations should the nurse expect with this diagnosis?
vova2212 [387]
The clinical manifestations should the nurse expect are reports of leg fatigue, tortuous veins in the legs and pain in lower extremities when standing.

In addition, leg fatigue is a communal clinical manifestation triggered by venous stasis and insufficient tissue oxygenation. The vein walls deteriorate and dilate causing distended, bulging veins that look tortuous and darkened. As vein walls weaken and dilate venous pressure increases and the valves turn out to be useless in which vein stasis and inadequate oxygenation end result is limb discomfort. The discolored toenails effect from a fungus below the nail or chronic hypoxia, not varicose veins, confined to a small area of heat in a calf is a mark of thrombophlebitis and reddened zones on a leg are symptomatic of thrombophlebitis.
