Membrane Transport and Active Transporters

L'importanza del trasporto a membrana
L'importanza del trasporto a membrana
The transport of solutes across the cell membrane is essential for metabolic processes, like maintaining cell size and volume, generating the action ...
Trasportatori a membrana
Trasportatori a membrana
Transporters are essential membrane transport proteins with functions related to cell nutrition, homeostasis, communication, etc. Approximately 7% of all ...
Trasporto Facilitato
Trasporto Facilitato
The chemical and physical properties of plasma membranes cause them to be selectively permeable. Since plasma membranes have both hydrophobic and ...
Trasporto attivo primario
Trasporto attivo primario
In contrast to passive transport, active transport involves a substance being moved through membranes in a direction against its concentration or ...
Pompe azionate ATP I: una panoramica
Pompe azionate ATP I: una panoramica
ATP-driven pumps, also known as transport ATPases, are integral membrane proteins. They have binding sites for ATP located on the membrane's cytosolic ...
ATP Driven Pumps II: Pompe di tipo P
ATP Driven Pumps II: Pompe di tipo P
The P-type pumps are a large family of integral membrane transporter ATPases. They are divided into five major types based on substrate specificity, from ...
ATP Driven Pumps III: Pompe a V
ATP Driven Pumps III: Pompe a V
V-type pumps are ATP-driven pumps found in the vacuolar membranes of plants, yeast, endosomal and lysosomal membranes of animal cells, plasma membranes of ...
ABC Transporters: Esportatore
ABC Transporters: Esportatore
ATP-binding cassette or ABC transporter is the largest superfamily of integral membrane proteins. The transporters have transmembrane-binding domains ...
ABC Transporters: Importatore
ABC Transporters: Importatore
ATP-binding cassette or ABC transporters are a class of ATP-driven pumps that hydrolyze ATP to move solutes across the membrane. They can be grouped into ...
Trasportatori di glucosio
Trasportatori di glucosio
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the ...
Trasporto attivo secondario
Trasporto attivo secondario
One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this ...
Trasporto transcellulare di soluti
Trasporto transcellulare di soluti
Transcellular transport of solutes is the movement of substances like monosaccharides and amino acids through polarized cells. This transport mechanism is ...
Assorbimento del glucosio nell'intestino tenue
Assorbimento del glucosio nell'intestino tenue
Complex carbohydrates consumed cannot be absorbed into the small intestine in their original form. First, they must be hydrolyzed to a monosaccharide form ...
Regolazione del pH dello stomaco
Regolazione del pH dello stomaco
The human body carefully regulates the internal pH of different organs to maintain homeostasis. For example, while the blood plasma maintains a neutral pH ...
