Which process describes the ATP requiring movement of extremely large sub substances out of a cell in pockets called vesicles?
The process that describes the ATP-requiring movement of extremely large substances out of a cell in pockets called vesicles is known as exocytosis. During exocytosis, vesicles containing the substances fuse with the cell membrane, releasing their contents into the extracellular space. This mechanism is crucial for processes such as neurotransmitter release and the secretion of hormones.
What else can I help you with?
All substances are this at very low temperatures?
All substances are in a solid state at very low temperatures, due to the very slow movement of their particles. This phenomenon is known as cryogenics, where materials are cooled to extremely low temperatures to achieve various scientific and practical purposes.
What property describes the plasma membrane's ability to regulate movement of molecules into and out of the cell?
Selective permeability is the property that describes the plasma membrane's ability to regulate the movement of molecules into and out of the cell, allowing only certain substances to pass through while restricting others. This selective permeability is achieved through the presence of various proteins and lipid components in the membrane.
Can passive membrane transport processes include movement of water from an area of low concentration to an area of high concentration?
No, passive membrane transport processes do not involve movement of substances from areas of low concentration to areas of high concentration. Instead, passive processes such as osmosis and diffusion move substances down their concentration gradient, from areas of high concentration to areas of low concentration without requiring energy input.
What membrane components allow movement of non-polar substances across membrane?
Integral proteins allow movement of non-polar substances across membranes.
What membrane indicates how easy it is for substances to cross?
The membrane that indicates how easy it is for substances to cross is the cell membrane or plasma membrane. This selectively permeable membrane regulates the movement of ions and molecules in and out of the cell, allowing certain substances to pass while blocking others. Its permeability is influenced by factors such as lipid composition, protein channels, and the presence of transport mechanisms. Overall, the fluid mosaic model describes the dynamic nature of the cell membrane in facilitating or restricting substance movement.
What does manoeuvrable mean?
a movement or action requiring dexterity and skill
What term describes the movement of continents?
The term that best describes the movement is gradual.
What Aids the movement of substances into and out of the cell.?
protein channels aid the movement of substances into and out of the cell.
What term best describes the movement of continents?
The term that best describes the movement is gradual.
Movement of substances from higher to lower concentration across a semipermeable membrane that must have a specific protein carrier but no energy expenditure is called?
Facilitated diffusion is the movement of substances from higher to lower concentration across a semipermeable membrane with the help of specific protein carriers, without requiring energy input.
What does manoeuvred?
a movement or action requiring dexterity and skill
What is the movement of substances?
any gas
Is the movement of substances against their concentration gradient an active or passive process?
The movement of substances against their concentration gradient is an active process.
All substances are this at very low temperatures?
All substances are in a solid state at very low temperatures, due to the very slow movement of their particles. This phenomenon is known as cryogenics, where materials are cooled to extremely low temperatures to achieve various scientific and practical purposes.

Selective permeability is the property that describes the plasma membrane's ability to regulate the movement of molecules into and out of the cell, allowing only certain substances to pass through while restricting others. This selective permeability is achieved through the presence of various proteins and lipid components in the membrane.
What controls movement of substances in and out of the cell?
osmosis
What is the vibration and movement of the atoms and molecules within substances called?
That is called thermal energy, which refers to the vibration and movement of atoms and molecules within substances.
