Mitochondria Definition and 19 Threads

I don't get, how option A corresponds to time point I. Electron transport/flow is independent of the phosphorylation, isn't it? Though it is not independent the other way round, i.e. the setting up of proton gradient requires the electron flow. I think the matching should have been: I-E, II-D...

The mitochondria has DNA code which being translated to protein in a certain amount. So how many proteins are from the mitochondria compared to the nuclues?

I was reading a science article and it mentioned in the future that scientist could engineer an artificial super mitochondria. The article is here. https://www.hindawi.com/journals/sci/2017/7610414/ I know the mitochondria generates energy and helps with respiration and the brief description...

I purposely added this post to the general physics thread rather than the biology thread because the solution is probably not in biology. Basically my PhD is in mitochondrial biology. Mitochondria are the energy producing organelles in the body which make energy by adding a chemical bond...

Paternal transmission of mitochondrial DNA (mtDNA) may be possible, a new study suggests – contradicting the accepted view that it is passed on exclusively through maternal inheritance. The find, made by a team led by Taosheng Huang from Cincinnati Children’s Hospital Medical Centre, and...

An important step in the evolution of plants, animals, and other complex, multicellular forms of life was eukaryogenesis, the evolution of eukaryotes. Eukaryotes are one of the three major classifications of life (alongside single-celled bacteria and archaea) and are characterized by cellular...

I've recently read a couple of papers on exercise and mitochondria (see e.g., http://www.sciencedirect.com/science/article/pii/S0891584907008349), in which state 4 and state 3 respiration rates and ROS production are assessed in vitro after exercise has been performed (i.e., rat heart...

I have noticed that cheetahs, peregrine falcons, and sailfish have similar mitochondria as far as amount of base pairs, genes, RNAs, and proteins. Cheetahs have in their mitochondria 17,047 base pairs, 13 genes, 24 RNAs, and 13 proteins. Their speed is up to 75 mph with their acceleration being...

I heard a claim bacteria can exist within human mitochondria, is there any evidence that is true ?. mitochondria"']https://www.google.com/search?q="bacteria+within+mitochondria"[/URL] only gets one hit, and the examples given are not human.

I am referring to "3 parents baby" discussed e.g. here http://www.economist.com/news/leaders/21565209-new-technique-help-cure-mitochondrial-diseases-should-be-permitted-law-powering . AFAIU they take the egg of mitochondria donor, remove its nucleus / DNA and transplant into it the mother's DNA...

While I have not yet found a satisfactory description of his research methods, I am aware that at the Nobel Prize winning biologist Otto Heinrich Warburg believed at least from 1924 to 1966 that cancer cells generate their ATP primarily from anaerobic metabolism. He was awarded the Nobel Prize...

can any of you explain this interest pattern? http://www.google.com/insights/search/#q=mitochondria&geo=US&cmpt=q

I was having a conversation with one of my family members about this. My biology education is limited as i did not focus on it in high school or in university. I understand that Mitochondira are considered the "energy factories" of a cell and that the term energy factory is not an accurate...

Some antibiotic kills bacteria by inhibiting their protein synthesis. The idea is that, prokaryotic and eukaryotic protein synthesis machinery is not the same, so we can selectively use antibiotic that inhibit bacterial protein synthesis but not ours. Mitochondrion also known as the powerhouse...

homework help... Homework Statement why mitochondria is called the power house of the cell? which is the site for protein syntesis in a cell?? Homework Equations The Attempt at a Solution I found out that mitochondria is the site for protein synthesis but I think its kinda...

Do mitochondria have like tiny nucleus? and if not how do they control their DNA replication and translation... thnx

Ok, so we all know that Mitochdiria contains its own DNA, mDNA, which codes for 13 of the approx. 80 needed proteins. We all know, that mutations in the mDNA almost always cause diseases in the central-nervous-system, heart and muscles. Now, I've been asked the following question: One of...

So this morning, I wokeup and thought "mitochondria!" Weird huh? Why? Well, I thought of it as just another "proof" of evolution from a common ancestor. Not that anyone with an education should doubt it anyway, but just that we and bacteria have the same intracellular organelles should be...
