What molecule stores the energy that is produced during cellular respiration? What nutrients do cells need to transport into the cell? What transports lipids to and from the adipocytes? What is a transport process that does not require the expenditure of cellular energy?
Step 1: Definition of Passive Transport - Passive transport is the movement of molecules across a cell membrane without the need for energy input. This process occurs along the concentration gradient, meaning substances move from areas of higher concentration to areas of lower concentration. ...
The meaning of PASSIVE TRANSPORT is the movement of substances (as by diffusion) across a cell membrane without the expenditure of energy.
This then buds off to the vesicle which contains the ingested material. Answer and Explanation: (a) The primary difference between active and passive transport is that active transport requires cellular energy whereas passive transport does not......
■■Large or hydrophilic molecules need to be transported across the membrane with the help of membrane proteins. ■■Facilitated diffusion is transport down a concentration gradient; it does not require energy. Active transport is transport up a concentration gradient; it requires energy. 56 3620001...
In passive transport, substances (e.g. ions and solutes) move across a membrane from a region of their higher concentration to a region of their lower concentration. The movement is described as downhill. Because of this, cellular energy (e.g. ATP) is not required as it is in active tr...
Passive:An Passive transport, also known as passive diffusion, is the process by which molecules or ions move across a cell membrane along their concentration gradient, from an area of higher concentration to an area of lower concentration, without the need for cellular energy expenditure. ...

Passive transport occurs when substances move down a concentration gradient from a higher concentration to a lower concentration. This does not require energy. Active transport occurs when a substance moves from a lower concentration to a higher...
