Yes. Transport that goes down a concentration gradient is spontaneous and therefore does not require energy.
No, passive transport does not require ATP because it moves molecules along their concentration gradient, from an area of higher concentration to an area of lower concentration. ATP is only required for active transport, which moves molecules against their concentration gradient.
Transport proteins such as ion channels and carrier proteins are used in both active and passive transport processes. Ion channels move ions down their concentration gradient through passive transport, while carrier proteins can facilitate passive transport by allowing molecules to move along their concentration gradient, or active transport by requiring energy to transport molecules against their concentration gradient.
Active transport requires energy and Passive transport requires no energy.Passive transport is a process which is carried out along the concentration gradient. For example, if the concentration of water is more outside the cell than inside, water will flow into the cell. Simply put, it is actually diffusion which occurs in passive transport and hence, no energy is required.Active transport, however, is carried out against the concentration gradient and hence requires energy. An example of active transport is the uptake of salt by cells through sodium pump.Active transport requires energy and moves particles up their concentration gradient. Passive transport doesn't require energy and moves particles down their concentration gradient.
Active transport requires energy input to move substances across a membrane against their concentration gradient, while passive transport does not require energy as it moves substances along their concentration gradient. Active transport is selective and requires specific transport proteins, while passive transport occurs through simple diffusion or facilitated diffusion.
PASSIVE TRANSPORT: when there is a transport of solutes from there higher concentration to their lower concentration across the semipermeable membrane as plasma membrane without any utilization of energy is called passive transport. ACTIVE TRANSPORT: When there is a net flow of solutes from there low concentration to their high concentrain of flow against the concentration gradiant with the utilization of energy is called active transport. e.g. Na+- K+ exchange pump.

A kind of transport by which ions or molecules move along a concentration gradient, which meansmovement from an area of higher concentration to an area of lower concentration.
The inter-membranous transport occurs in two ways: 1) Active Transport: occurs against the concentration gradient, Expenditure of energy occurs. 2) Passive transport: Refers to phenomena wherein transfer occurs along the concentration gradient i.e. from high concentration to low concentration, without any expenditure of energy.

Active transport requires energy input to move molecules against their concentration gradient, while passive transport does not require energy and moves molecules along their concentration gradient. Active transport usually involves the use of transport proteins, such as pumps or carriers, while passive transport relies on diffusion or facilitated diffusion.
Bulk transport, also known as bulk flow or vesicular transport, can occur in both directions relative to the concentration gradient. When substances are moved against their concentration gradient, this process is typically active transport, requiring energy (usually in the form of ATP). Conversely, when substances are moved along their concentration gradient, it is considered passive transport. Overall, bulk transport encompasses mechanisms that can handle both scenarios.
When a molecule enters the cell through a protein pump, it is classified as active transport. This process requires energy, typically in the form of ATP, to move molecules against their concentration gradient, from areas of lower concentration to higher concentration. In contrast, passive transport does not require energy and occurs along the concentration gradient.
Any form of transport that does not require a form of energy, which means that it happens along a concentration gradient (from an area of high to low concentration) and across a selectively permeable membrane (Osmosis)
Active transport and passive transport are two methods by which substances move across cell membranes. Active transport requires energy, typically in the form of ATP, to move molecules against their concentration gradient, while passive transport does not require energy and occurs along the concentration gradient. Both processes are essential for maintaining cellular homeostasis, but they differ in their energy requirements and the direction in which substances move relative to their concentration gradients.
Active transport requires energy input to move molecules against their concentration gradient, while passive transport moves molecules along their concentration gradient without energy input. Active transport is typically carried out by transport proteins, such as pumps, while passive transport can occur through simple diffusion or facilitated diffusion.
