ATP is a nucleotide that consists of three main structures: the nitrogenous base, adenine; the sugar, ribose; and a chain of three phosphate groups bound to ribose. The phosphate tail of ATP is the actual power source which the cell taps. Available energy is contained in the bonds between ...
Each heavy chain is comprised of an N-terminal motor domain that contains the ATP- and actin-binding sites, an intermediate rod domain that dimerizes to form an α-helical coiled-coil and a C-terminal tailpiece. Despite the fairly high sequence conservation between the non-muscle myosin-II ...
Following its synthesis in the liver and intestines, ApoA-I mediates this transportation by the formation of high density lipoprotein (HDL) particles. These load cholesterol and lipids from macrophages at the artery wall via a regulated efflux mechanism catalyzed by the cellular ATP-binding cassette ...
Biology A level OCR - Eukaryotic Cell Structure. This is following the OCR textbook for A level biology. The cheat sheet is on module 2, foundations in biology. Cells There are two fundamental types of cells: prokaryotic and eukaryotic. ...
underlie some forms of long-QT syndrome. This syndrome is characterized by a prolongation in the depolarization time-course of cardiac myocyte action potentials, which can lead to fatal arrhythmias. In addition, mutations inadenosine triphosphate(ATP)-sensitive potassium channels that controlinsulinsecreti...
Biology Biology Article CellsCells1,77,257 Cells are the basic, fundamental unit of life. So, if we were to break apart an organism to the cellular level, the smallest independent component that we would find would be the cell. Explore the cell notes to know what is a cell, cell ...
The function of the TOC-TIC supercomplex has been characterized by its association with the model preproteins in intact chloroplasts in the presence of ATP and/or GTP (Kikuchi et al., 2013; Ramundo et al., 2020; Schleiff et al., 2003). We further tested the interaction between the purifi...
The sarcomeric interaction of α-myosin heavy chain (α-MHC) with Titin is vital for cardiac structure and contraction. However, the mechanism regulating this interaction in normal and failing hearts remains unknown. Lactate is a crucial energy substrate of the heart. Here, we identify that α-...
In this work, we have assessed the exposure of soil bacteria from potato monoculture to three types of silver nanoparticles (AgNPs) as well as silver ions (Ag+ ions) delivered in the form of silver nitrate and a commercially available fungicide. The diversity of the soil microbial community, ...
7.8: Idrolisi dell'ATP I legami dell'adenosina trifosfato (ATP) possono essere spezzati attraverso l'aggiunta di acqua, rilasciando uno o due gruppi di fosfati in un processo esergonico chiamato idrolisi. Questa reazione libera l'energia nei legami per l'uso nella cellula, ad esempio ...
