Determine which complex of the electron transport chain (respiratory chain) each phrase describes. (coenzyme q is also called ubiquinone or ubiquinol, depending on whether it is in oxidized or reduced form.)

complex i:

complex ii:

complex iii:

complex iv:

here are the choices that need to be put in the correct complex:

1) nadh-ubiquinone(nadh-coenzyme q oxidoreductase)

2) coenzyme q-cytochrome c oxidoreductase

3)electron transfer from succinate to ubiquinone (coenzyme q)

4) electron transfer from cytochrome c to o2

5) succinate-coenzyme q oxidoreductase (succinate dehydrogenase)

6) cytochrome c oxidase

7) electron transfer from ubiquinol (qh2) to cytochrom c

8) electron transfer from nadh to ubiquinone (coenzyme q)

Calculate the number of kilojoules to warm 125 g of iron from 23.5°c to 78.0°c.

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)

What is the relationship between wind and ocean waves? question 17 options: wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves. wind moving at higher speeds will transfer energy over a larger part of the ocean water, resulting in waves with a shorter wavelength. winds moving at higher speeds with cause water to move forward at faster rates, causing larger ocean waves. winds moving at higher speeds will affect deeper water, resulting in waves that move at a faster rate. how do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
