The Biochemical Journal. I need lots of food in the way that fat cells need a lot of mitochondria to give them energy. For example, mitochondria in liver cells contain enzymes that allow them to detoxify ammonia , a waste product of protein metabolism.
The Journal of Bone and Joint Surgery. All Performance.
As mitochonderia is power house of the cell. All Cycling. Rejuvenation Research. It was not until , when David Keilin discovered cytochromes , that the respiratory chain was described.
Mitochondria are special because they have their own ribosomes and DNA floating in the matrix. Magnetococcus marinus. The mitochondria take both of these ingredients, also called substrates, and use them to produce the energy product that makes your heartbeat and your muscles perform.
Mitochondrion - Wikipedia
Your answer makes a lot of sense, and I agree that it is very likely going to be muscle cells, but neither of your references support it. ADP returns via the same route. Instead, this mitochondrial-ER interface emphasizes the integration of the mitochondria, the product of an endosymbiotic event, into diverse cellular processes.
These enzymes include monoamine oxidase , rotenone -insensitive NADH-cytochrome c-reductase, kynurenine hydroxylase and fatty acid Co-A ligase. Under certain conditions, protons can re-enter the mitochondrial matrix without contributing to ATP synthesis. These anaplerotic and cataplerotic reactions will, during the course of the cycle, increase or decrease the amount of oxaloacetate available to combine with acetyl-CoA to form citric acid.
Chalk Talk: Inside your muscle cell there are tiny little fibrils essentially filaments of protein called Actin and Myosin. Which of the cell types commonly found in mammals has the greatest number of mitochondria? Experimental Gerontology. Contraction and Relaxation in a muscle is done by a process called Excitation contraction coupling, which requires ATP. In the Star Wars franchise, microorganisms referred to as "midi-chlorians" give some characters the ability to sense and use the Force.
Cell-level selection may then act to remove those cells with more mutant mtDNA, leading to a stabilisation or reduction in mutant load between generations. Double-strand breaks can be repaired by homologous recombinational repair in both mammalian mtDNA  and plant mtDNA. It is clear that the enzymes necessary for recombination are present in mammalian cells. Athletes' Choice. Topic Editors. Ask Question. So, which cell type will have the greatest number of mitochondria?
Mitochondria Explained Mitochondria are affectionately referred to in almost every academic physiology textbook as the powerhouses of the cell. Since mitochondria have many features in common with bacteria , the endosymbiotic hypothesis is more widely accepted.
This also explains why your breathing rate increases; to provide the oxygen, needed for respiration, to the many mitochondria to produce energy.
