Значение мембранного транспорта
Значение мембранного транспорта
The transport of solutes across the cell membrane is essential for metabolic processes, like maintaining cell size and volume, generating the action ...
Мембранные транспортеры
Мембранные транспортеры
Transporters are essential membrane transport proteins with functions related to cell nutrition, homeostasis, communication, etc. Approximately 7% of all ...
Облегченный транспорт
Облегченный транспорт
The chemical and physical properties of plasma membranes cause them to be selectively permeable. Since plasma membranes have both hydrophobic and ...
Первичный активный транспорт
Первичный активный транспорт
In contrast to passive transport, active transport involves a substance being moved through membranes in a direction against its concentration or ...
Насосы с приводом от ATP I: обзор
Насосы с приводом от ATP I: обзор
ATP-driven pumps, also known as transport ATPases, are integral membrane proteins. They have binding sites for ATP located on the membrane's cytosolic ...
Насосы с приводом от ATP II: насосы P-типа
Насосы с приводом от ATP II: насосы P-типа
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 ...
Насосы с приводом от ATP III: V-образные насосы
Насосы с приводом от ATP III: V-образные насосы
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: Экспортер
ABC Transporters: Экспортер
ATP-binding cassette or ABC transporter is the largest superfamily of integral membrane proteins. The transporters have transmembrane-binding domains ...
ABC Transporters: Импортер
ABC Transporters: Импортер
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 ...
Транспортеры глюкозы
Транспортеры глюкозы
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the ...
Вторичный активный транспорт
Вторичный активный транспорт
One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this ...
Трансцеллюлярный транспорт растворенных веществ
Трансцеллюлярный транспорт растворенных веществ
Transcellular transport of solutes is the movement of substances like monosaccharides and amino acids through polarized cells. This transport mechanism is ...
Всасывание глюкозы в тонкую кишку
Всасывание глюкозы в тонкую кишку
Complex carbohydrates consumed cannot be absorbed into the small intestine in their original form. First, they must be hydrolyzed to a monosaccharide form ...
Регулирование pH желудка
Регулирование pH желудка
The human body carefully regulates the internal pH of different organs to maintain homeostasis. For example, while the blood plasma maintains a neutral pH ...
