Cholesterol acts as the precursor to steroid molecules many of which function as hormones.
Often on television shows and in articles I see it mentioned that it'd always be bad to blow up an asteroid or comet because then the energy would just be spread out and cause even more damage.
According to some estimates I've seen around 100 tons (or more) of meteoroids hit the Earth each day. If all of this were combined together into a single asteroid, it could destroy an entire, large city.
Given that alone, it makes it seem to me that it be more logical to take the chance and blow up an asteroid and thereby trim its weight down, causing a lot more to be more easily burnt up on entry, so that when it did hit, it would cause less damage.
Is this logical at all? If my science/math/physics is incorrect, I want to understand why having more burn up by spreading out is worse compared to having it more concentrated and vastly more dangerous.
Following Statements Accurately describe the electron transport chain (ETC)
- Proton transport from the matrix to the intermembrane space is connected with electron transfer in the electron transport chain (ETC).
- Prosthetic groups, like iron-sulfur centers, are directly engaged in the transport of electrons.
- Small molecules and hydrogen ions can easily pass through mitochondria's outer membrane.
- Four complexes of proteins and prosthetic groups make up electron carriers.
- Ubiquinone (coenzyme Q) and cytochrome c are electron carriers in the electron transport chain (ETC).
The oxidative phosphorylation process, also known as the electron transport chain (ETC), is a collection of four protein complexes that combine redox events to produce an electrochemical gradient that results in the production of ATP. Both photosynthesis and cellular respiration take place in mitochondria.

Exchange of materials and house genetic material.. i'm not sure if this is right though
