How does diffusion, energy conversions, and protein synthesis relate to cellular homeostasis.

Can you explain this to me in detail with examples but easy enough for me to understand.

-> Honors: "In 175 words or more, explain in detail (and with examples) how diffusion, energy conversions, and protein synthesis relate to cellular homeostasis."

-> CP: "In 125 words or more, explain in detail (and with examples) how diffusion, energy conversions, and protein synthesis relate to cellular homeostasis.

Let me know too while you at it. hahaha

Homeostasis is to maintain the internal environment of the body stable,,
At the cell level there is a work of a process to keep the intracellular fluid and the extracellular fluid in a balanced level and this worked out by the wall turgor pressure and the concentration of substances in those sites and that is called the osmosis...and as an e.g. the change in the concentration of sodium, potassium...etc. inside the cell will lead to the passive diffusion work to let the water enter to the inside of the cell and vice versa (if decrease inside the water goes outside)..
And this explains the relation between the diffusion (simple\passive) and the cell homeostasis...
For the relation between the energy conversion and cell the example of muscle at exercises and the need of oxygen are useful..
Once the muscle cells (skeletal) suffocate from the no oxygen and no energy perform...the lactic acid fermentation work to cover this need to form the needed O2 and the needed ATP later on and because of that the lactase appear and this form pain and muscle fatigue and those resulting on a signal to brain to stop the exercise and to allow more O2 to enter the lung to form energy via that.. And by the stop the lactase carried out from the muscle and pain stop...
(in summery...the need of energy and no O2 so a new source of energy appear (lactic...)and form lactase when the need stop the brain signal work to stop this new source of energy and get rid of the side effect that appeared by the lactase and get rid of it also)
You can use the simplest example of the homeostasis by the body need of energy at stress so the body when the body use more energy for that action and use more glucose and transfer ADP to ATP and once he is in relax state he got rid of all waste and change to the store function and remove waste and the back to keep the energy sources in storage forms…
For the protein synthesis I can’t give any clear example but the body at starvation state to metabolize the protein to form energy and when the patient has the supplement and no need for the protein the body start to form it into muscle and so
This for the metabolism
But for the synthesis this appear according to the need of enzymes in any situation and later the destruction goes when no need or just get rid of it to the amino acids….

You can make the example of exercise as the mix example for the 3 together>>
The need of energy in cell and the work inside it to form proteins and the waste with the change of the concentrations inside the cell….
And then use the negative feedback and positive feedback in all that to make a mixed example….
This is all what I can try to use from what they explained to me….
