Howdy first post. Why is it said that life needs water to develop. Everybody says that life hear came from the sees but why could it come from a methane sea? or even beyond that on a gas planet?
Thanks Ryan
Thanks Ryan
Why would that eliminate all others?Monique said:Water is a great solvent with a high di-electric constant.

The special condition is in the mitochondria, along the respiratory electron transport chain. Electrons formed during the oxidation of glucose are passed along the electron transport chain to electron accepting molecules embedded in the mitochondrial membrane. These molecules then produce free protons, which ultimately drive ATP synthesis.Minorail said:I think only under some specil condition will oxigen form radicals, or all of us should not live same this.
again never such posibility. u heard of any case which patien poinsoned by what you said. i think such way of explaining is not correct. and misleding people to wrong assumption.It is possible that by mistake the electron is accepted by molecular oxygen (O2), leading to the formation of superoxide free radicals (O2.-). It is said that this electron leak converts about 1-3% of oxygen molecules into superoxide.
I'm not sure what you just said here.Minorail said:What you nmean ? do you think you are trying toi be correctly stating it or just kind of metaphor explaning how atigen antibody tcell.in action ?
It is a proton gradient that drives ATP synthesis. Due to the gradient that is set up by the electron transfer, protons start moving from one side of the membrane to the other. They move through channels of ATP synthase, a very clever molecule. You can see the process happening in this animation http://www.sp.uconn.edu/~terry/images/anim/ATPmito.html you can see the electron transport here http://www.sp.uconn.edu/~terry/images/anim/ETS.htmlby the way, i think saying ATP synthesis is driven by proton sound really strange, this stuff must be in enzyme instead.
That is the problem: the radicals are very reactive and will attack the proteins that are next to it, the fact that we have enzymes such as SOD (superoxide dismutase) shows that the free radicals need to be neutralized before they react with something else.Minorail said:again never such posibility. u heard of any case which patien poinsoned by what you said. i think such way of explaining is not correct. and misleding people to wrong assumption.
such chemica reaction true it can happen in nature, universe around us, radical soon destroyed in air or in human body by other oxygen atom or molecula
Saying oxygen is harmful to life (not that I'm claiming you said that...) is like saying gasoline is harmful to cars. Any fuel source is, by definition, capable of releasing its energy in unproductive and harmful ways. Even when released in productive ways there are still undesirable side effects. You still want the oxygen/gasoline, because otherwise you're just a doorstop. It's just not a perfect energy source.Monique said:The problem with oxygen is that it forms free radicals, very toxic to life. Oxygen is a very good electron acceptor, as Phobos said, but the release of energy from oxygen is very explosive; the energy that can be extracted from it would be very inefficient without the electron transport chain in the mitochondria, which tap the energy step by step.

Methane seas and gas planets are celestial bodies that are primarily composed of gases, such as methane and hydrogen. They are often found in the outer regions of our solar system and are significantly larger than rocky planets like Earth.
Scientists believe that methane seas and gas planets form through a process known as accretion. This is when small particles, such as dust and ice, come together to form larger bodies due to gravity. As these bodies grow, they can attract more gas and eventually become gas planets.
It is currently unknown if life could exist on methane seas and gas planets. These environments are vastly different from Earth, and the extreme conditions, such as high pressure and lack of oxygen, make it challenging for life as we know it to survive. However, some scientists theorize that microbial life could potentially exist in these environments.
Scientists study methane seas and gas planets using a variety of methods, including telescopes, spacecraft, and computer simulations. Telescopes allow us to observe these bodies from a distance, while spacecraft can gather data and images up close. Computer simulations also help us understand the formation and evolution of these planets.
Studying methane seas and gas planets can provide insights into the conditions and processes that were present during the early stages of our solar system's formation. This can help us understand how life may have originated on Earth and potentially on other planets in our galaxy. Additionally, the search for life on these bodies can expand our understanding of the diversity of life in the universe.
