The distinction between active and passive transport processes is primarily determined by the energy requirement and the concentration gradient. Active transport requires energy input, usually from ATP, to move substances against their concentration gradient, while passive transport occurs spontaneously, driven by the natural movement of molecules from areas of higher concentration to lower concentration, without the need for energy. Additionally, the presence of specific transport proteins may also influence the type of transport process.

What determines whether molecules diffuse into or out the blood?
Molecules diffuse into or out of the blood primarily based on their concentration gradients, size, and solubility. Substances move from areas of higher concentration to lower concentration, a process known as passive diffusion. Additionally, membrane permeability plays a role; small, nonpolar molecules can easily cross cell membranes, while larger or polar molecules may require specific transport proteins. Other factors, such as temperature and the presence of active transport mechanisms, also influence diffusion rates.
Do passive transport mechanisms use integral proteins to move substances through membranes?
Yes they may. Passive or Active can both use integral proteins to facilitate transport. When the substances are transported from low to high concentration it requires additional energy (i.e. active transport); while passive transport move molecules from high concentration to low and do not need additional energy (passive transport). Integral proteins are membrane proteins that have transmembrane domain, but whether it will need energy (ATP, photons or conc. gradient) to change from inactive form to active form depends on the substance that it is transporting.
What are five transport mechanism where by metabolites nutrient or ions cross the cell membrane?
There are many forms of membrane and cell transport. These are the basic transport mechanisms in a prokaryotic animal cell. Facilitated Diffusion Osmosis Diffusion Exocytosis (this takes two forms; phagocytosis and pinocytosis depending on whether the cell is "eating" or "drinking") Endocytosis Carrier Molecules/Channel Proteins
Ions can move through water by what process?
It depends whether by "channels" you mean channel proteins or ion pumps.Substances that move through channel proteins do so by facilitated diffusion. This is diffusion, and therefore is passive (it requires no energy input from the cell). It is called facilitated, because the substances cannot pass through the phospholipid bilayer, and so their passage across the membrane is facilitated by the channels.Ion pumps are different. They move ("pump") a substance against its concentration gradient. This does require a supply of energy, and the cell may supply this by breaking down ATP. The process is called active transport, and can only occur in carrier proteins. Ion pumps are one form of carrier protein.
What determines the properties of solution?
Whether or not it's an acid or a base
Does the process of transport, whether passive or active, require energy?
Yes, the process of transport, whether passive or active, requires energy.
What energy is required for passive transport?
By definition, passive transport on a cellular level requires no energy other than some sort of gradient, whether of the molecule in question, or another whose movement across the membrane can be linked to the one of interest.
Is diffusion passive or active transport?
Diffusion is passive, it happens everywhere whether living things are involved or not. It results from the natural thermal motion of particles.
What are the passive transport?
Passive transport processes do not require ATP or energy for transport. Co-transport processes would also not be considered a passive process. -The xylem in plants uses capillary action, a passive process -If a specific channel exists for, let's say, an ion or molecule, then that channel uses passive transport, however, it the channel cannot be "gated" in any way as in voltage-gated Na+ channels or delayed rectifier K+ channels. You can also look at the ascending loop of Henle in the juxtamedullary nephron of the kidney and see passive transport of water molecules -The blood brain barrier also allows passive transport of certain molecules A good way to think of passive transport is whether or not the plasma membrane has "holes" big enough in it to allow for molecules to pass through, provided there are no charge hindrances for that molecule passing through. Or a specific channel is open and letting a molecule in without the expense of ATP (using ATP to make the membrane channel protein does not fall under this category)
Does glucose need a transport protein?
Depends if it goes into the cell or out of the cell whether it is passive or active. Yes.

What are two important passive processes for membrane transport?
Diffusion is a method of natural movement of gas molecules from a region of higher concentration to a region of lower concentration. The difference in concentration is called a concentration gradient.Osmosis is the diffusion of water through a biological membrane. Water molecules move along the concentration gradient from the area of higher water concentration to lower concentration.Facilitated diffusion is when proteins within the cell carry or escort certain materials or substances in or out of the cell.
What process determines whether or not an imitated or modeled act will be repeated?
The reinforcement process determines whether an imitated or modeled act will be repeated. If the imitated behavior results in a positive outcome or reward, it is more likely to be repeated. Conversely, if the behavior leads to negative consequences or no payoff, it is less likely to be replicated.
Do passive transport mechanisms use integral proteins to move substances through membranes?
Yes they may. Passive or Active can both use integral proteins to facilitate transport. When the substances are transported from low to high concentration it requires additional energy (i.e. active transport); while passive transport move molecules from high concentration to low and do not need additional energy (passive transport). Integral proteins are membrane proteins that have transmembrane domain, but whether it will need energy (ATP, photons or conc. gradient) to change from inactive form to active form depends on the substance that it is transporting.
What determines whether it will float in water?
Whether your foot is on it or not.
Which best describes the president's role in the federal legislative process?
The president determines whether to sign or veto bills passed by Congress.
