Transportation system aquatic living organisms (10) includes a container (12) for holding (16) aquatic living organisms in one or more animal and an amount of water. (24) cooperate oxygen supply system and control system (17) to supply oxygen at a rate needed to maintain the selectable ...
is an effectivetransportsystemfor microscopic organisms‚ but multicellular organisms require a more complextransportsystemto sustain itself. Take humans for example; unlike a cell‚ only the outer layer of skin is in contact with the body’s outside environment. It’s not possible for ...
Recognized by their common modular organization and two sequence motifs that constitute a nucleotide binding fold, ABC transporters are widespread among all living organisms. They accomplish not only the uptake of nutrients in bacteria but are involved in diverse processes, such as signal transduction,...
In most cases of plasma membrane primary active transport in eukaryotic organisms, the energy is provided by the hydrolysis of ATP, a process catalyzed by the same molecule that performs the transport. Hence, in this case the transporter is also an ATP hydrolase (ATPase). Transporters responsible...
“An economic community supported by a foundation of interacting organizations and individuals – the organisms of the business world. The economic community produces goods and services of value to customers, who are themselves members of the ecosystem. The member organisms also include suppliers, lead...
Despite their central role in CCM function, inorganic carbon (Ci) transport systems never have been identified in eukaryotic photosynthetic organisms. In the green alga Chlamydomonas reinhardtii, a mutant, pmpl, was described in 1983 with deficiencies in Ci transport, and a Pmpl protein-associated ...
We describe here the application of a more general method, namely the measurement of electron transport system activity, to estimate in situ rates of oxygen utilization in macrobenthic invertebrates. DESCRIPTION OF THE ELECTRON TRANSPORT SYSTEM All organisms that respire do so through a respiratory ...
Many transport systems, have been identified and fully characterized over the years in a wide variety of living organisms, with the bacterial lactose permease (LacY) and the potassium channels (KcsA) being frequently at the forefront of such studies (Kaback, 2005; Doyle et al., 1998). However...
