Large-scale active transport refers to the movement of substances across cell membranes against their concentration gradient, requiring energy input, typically from ATP. This process is essential for maintaining cellular homeostasis and involves mechanisms like endocytosis and exocytosis, which allow cells to engulf large particles or expel materials. Unlike simple diffusion, large-scale active transport can handle larger volumes and complex materials, playing a crucial role in nutrient uptake, waste removal, and intercellular communication.

What is the name of two large scale forms of active transport?
Two large-scale forms of active transport are endocytosis and exocytosis. Endocytosis involves the engulfing of substances into the cell by wrapping them in a section of the cell membrane, while exocytosis is the process of expelling materials from the cell by vesicles fusing with the membrane. Both processes require energy, typically in the form of ATP, to move substances against their concentration gradient.
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
What do cells that secrete large amounts of substances via active transport need a large amount of in their cytoplasm?
Cells that secrete large amounts of substances via active transport need a large amount of energy in the form of ATP in their cytoplasm. Active transport mechanisms require energy to move molecules across the cell membrane against their concentration gradient. This energy is generated in the cell through processes such as cellular respiration.
How does active transport differ from passive transport-?
Active transport requires energy while passive transport does not.
Is pinocytosis acitve or passive transport?
It is the active transport of liquids in vesicles into and out of a cell so it uses metabolic energy, thus active
Does passive transport requires large amounts of energy?
No. only active transport does

How do large food particles enter amoeba?
Active transport
What occurs if substances are too large to pass through the cell membrane by active or passive transport?
passive transport
What type of molecule embedded in the cell membrance allows larger molecule to pass through the membrance by active transport?
Transport proteins allow the active transport of large molecules through the cellular membrane.
What can large particle can enter a cell by an active-transport process?
The cell Wall
What is a good sentence for Active Transport?
Active Transport is carried out in our body cells. Active Transport uses energy to transport materials.
Is testosterone a passive transport or an active transport?
it is an ACTIVE transport.
Is an active transport active or passive?
It has is in the name. Active Transport
