答案:Mitochondria are often referred to as the "powerhouses" of the cell because they generate most of the cell's supply of adenosine triphosphate (ATP), which is used as a source of chemical energy. They are unique among cellular organelles because they have their own mitochondrial DNA and ...

Mitochondria stand as the principal metabolic centers for cellular energy, generating ATP through OXPHOS to meet the cell’s energy needs [41]. A notable byproduct of this process is the generation of ROS, primarily produced by mitochondria during normal aerobic respiration [42,43]. Approximately ...
These experiments revealed that, upon cell stimulation, mitochondria can accumulate high amount of Ca2+, reaching [Ca2+] much higher than those in the cytosol and largely above those expected by the MCU properties. The discrepancy between the low Ca2+ affinity of MCU and the mitochondrial matrix...
Which feature have these prokaryotes lost during their evolution into mitochondria? A cell wall B circular chromosome C internal membranes D ribosomes 7 A student carried out the Benedict’s test on a sample and got a negative result. What should the student do to confirm there are no sugars...
Although some studies have been conducted over the past few decades, the existence of mitochondria-rich cells (MRCs) in reptiles is still obscure. This is the first study to uncover the presence of MRCs in the small intestine of Chinese soft-shelled turtles. In this study, we i...
Group-specific functional patterns of mitochondrion-related organelles shed light on their multiple transitions from mitochondria in ciliated protists Article21 November 2022 Heterotrophic euglenidRhabdomonas costataresembles its phototrophic relatives in many aspects of molecular and cell biology ...
mitochondria acquire other phospholipids, such as phosphatidylserine (PS), from the ER through MAM, which are key precursors for the synthesis of PE [34]. PS is synthesized by phosphatidylserine synthase (PSS) in the ER and is transported to the cell membrane and mitochondria through lipid transf...
Our findings identify mitopherogenesis as a previously undescribed process for mitochondria-specific ectocytosis, which may represent a fundamental branch of mechanisms underlying mitochondrial quantity control to regulate cell functions during development....
