How temperature affects active transport?

Answer 1

Temperature always changes the rate of any reaction. An increase in temperature will increase the rate while decrease will slow a reaction.

Answer 2

concentration of oxygen

concentration of glucose

temperature

(they all affect the rate of respiration and hence affect the rate of active transport)

Note that surface area can also affect the rate as the # of protein carriers will increase with increase in surface area.

Answer 3

An increase in temperature can generally increase the rate of active transport as it provides more kinetic energy for the transport proteins to move molecules against their concentration gradient. However, extremely high temperatures can denature the transport proteins, leading to a decrease in active transport efficiency. Conversely, lower temperatures can slow down active transport due to decreased kinetic energy available for the transport process.

Answer 4

The types of materials that have to get in the cell, for ex. some may be too big to fit through the protein.

A better answer is:

The factors that affect the rate are the size of the gradient, molecular size, charge, and lipid solubility. Sorce: http://www.innvista.com/health/anatomy/celltran.htm

Answer 5

Well when the temperature gets really high and it gets hot, the molecules go faster and it goes from an area of to low concentration to an area of high concentration. When the temperature gets low and its colder, then the molecules move slower and it goes from an area of low concentration to high concentration.

Answer 6

Oxygen concentration: change in pH. Glucose concentration. Enzyme inhibitors. Temperature

Answer 7

Membrane pore size, temperature and electric charge

Answer 8

Factors affecting activation energy are:- temperature- frequecy of collisions between molecules- catalysts- reaction rate constant

Answer 9

Molecular weight

Answer 10

energy use
