Factors that can increase the rate of mediated transport include an increase in the concentration gradient of the substance being transported, an increase in the number of transport proteins available, and an increase in the efficiency of the transport proteins. Additionally, factors such as temperature and pH can also affect the rate of mediated transport.
Carrier-mediated transport can be either passive or active, depending on the type of carrier protein involved. Passive carrier-mediated transport allows molecules to move down their concentration gradient without requiring energy input, while active carrier-mediated transport moves molecules against their concentration gradient using energy from ATP or an electrochemical gradient.
Vesicle-mediated transport is a type of intracellular transport where cellular materials are moved within a cell using membrane-bound vesicles. This process allows for the transport of molecules such as proteins, lipids, and other substances between different organelles within the cell or between the cell and its external environment.
It is not depenent on a concentration gradient.
Water can cross cell membranes through both channel-mediated diffusion and simple diffusion. While aquaporins, specialized water channels, facilitate rapid water transport, water molecules can also passively diffuse through the lipid bilayer, albeit at a slower rate. Thus, while channel-mediated diffusion is a significant route for water movement, it is not the only one.
Yes, when channels are specific for the structures of individual molecules it is active transport. Active transport cannot occur if the energy they are moving is not of the same type, like glucose cannot move calcium.

Passive carrier-mediated transport allows molecules to move down their concentration gradient without requiring energy input, while active carrier-mediated transport moves molecules against their concentration gradient using energy from ATP or an electrochemical gradient.

Respiration rate increases to supply more oxygen to cells and remove excess carbon dioxide produced during increased energy demand. Active transport rate increases to facilitate the movement of essential molecules across cell membranes against a concentration gradient to maintain cellular functions and homeostasis.

An activator is a person who activates, or any of various types of chemical - a chemical which regulates genes by increasing the rate of transcription, or a type of effector which increases the rate of enzyme-mediated reactions.
The progressive tax rate is one where the tax rate increases as the taxable rate, or income, is increasing.

Elevating your heart rate increases your basal metabolic rate in an individual.
During hemorrhage, the body experiences a decrease in blood volume, leading to reduced blood pressure. To compensate for this drop and maintain adequate blood flow to vital organs, the heart rate increases. This response is mediated by the autonomic nervous system and hormones like adrenaline, which stimulate the heart to pump more frequently and forcefully, aiming to stabilize circulation despite the loss of blood.
