Answer:

An increase of 3,500 J

Explanation:

Given that,

Energy added by swimmer = 12000 J

Heat removed by the surrounding = 8500 J

We need to find the total change in energy. It can be calculated using the law of conservation of energy such as :

\Delta U=Q-W\\\\\Delta U=12000-8500\\\\\Delta U=3500\ J

As the change in energy is positive, it means that there is an increase of 3500 J.

bagirrra123 [75]


The term is Facilitated diffusion.

Facilitated diffusion is a transport mechanism in which carrier proteins shuttle molecules across the cell membrane without using the cell's energy, and because it does not use the cell's energy, it is a passive transport.

The energy is provided by the concentration gradient, which means that molecules are transported from higher  to lower concentrations, into or out of the cell.

The carrier proteins of the GLUT family are responsible for transporting glucose. They bind to glucose , which causes them to change shape to fit in the membrane passage then they translocate the glucose molecule from one side of the membrane to the other.

Red blood cells use facilitated diffusion to absorb glucose.

This occurs as a result of decrease in the concentration of Hydrogen ion, which results to increased bicarbonate in the body system. It can also be caused by direct increase in the bicarbonate concentrations.
