Which of the following statements regarding active transport is false?
Tue Jan 08 2002 13:30:00 GMT-0500 (Eastern Standard Time) · Facilitated diffusion (also known as facilitated transport or passive-mediated transport ) is the process of spontaneous passive transport (as opposed to active transport ) of molecules or ions across a biological membrane via specific transmembrane integral proteins. Being passive facilitated transport does not directly require chemical energy from ATP hydrolysis in the transport step itself ...
The automatic identification system (AIS) is an automatic tracking system that uses transceivers on ships and is used by vessel traffic services (VTS). When satellites are used to detect AIS signatures the term Satellite-AIS (S-AIS) is used. AIS information supplements marine radar which continues to be the primary method of collision avoidance for water transport .
Cystic fibrosis transmembrane conductance regulator (CFTR) is a membrane protein and chloride channel in vertebrates that is encoded by the CFTR gene.. The CFTR gene codes for an ABC transporter-class ion channel protein that conducts chloride ions across epithelial cell membranes.Mutations of the CFTR gene affecting chloride ion channel function lead to dysregulation …
The ATP-binding cassette transporters (ABC transporters) are a transport system superfamily that is one of the largest and possibly one of the oldest gene families.It is represented in all extant phyla from prokaryotes to humans.. ABC transporters often consist of multiple subunits one or two of which are transmembrane proteins and one or two of which are membrane-associated AAA ATPases.
Chemotaxis (from chemo-+ taxis) is the movement of an organism in response to a chemical stimulus. Somatic cells bacteria and other single-cell or multicellular organisms direct their movements according to certain chemicals in their environment. This is important for bacteria to find food (e.g. glucose) by swimming toward the hi...
