Yes. I'm sorry if I may sound naive but it's only because my background is in biology. I only just started exploring physics. Cancer cells generally show a massive rise in entropy and are exergonic.shjacks45 said:"Is it possible to limit the entropy generation in a biological system using an engine?" Can you explain which "biological system" you are replacing? Can you reference a Carnot cycle engine that actually exists?
Do you mean to say that we'll have to replace the whole system with an engine? Does that mean replacing a complete tumor?shjacks45 said:"Is it possible to limit the entropy generation in a biological system using an engine?"

Still don't understand why one needs to control the entropy in a biological system. A tumor is a normal cell whose feedback mechanisms controlling growth are damaged. There are no new or different cell mechanisms. Tumors are often fast growing, and will probably be warmer due to metabolic activity. I have never seen cancer research refer to a tumor's "entropy". Antimetabolic drugs/radiation affects other fast growing cells like hair. Skin, and intestinal lining; as well as tumor cells. At first I thought you were looking to replace mitochondria to make cells more efficient. But you can't just couple a shaft like a physical engine, you would need to address the thousands of (but finite) chemical and DNA connections that cells have with mitochondria. Note the same less efficient energy pathways like glucose-6-phosphate shunt is used by red blood cells.vjrajsingh said:Yes.

And I know Carnot engines don't exist practically. I'm only asking if it's possible in theory to use a bioengine that works along these same principles to turn entropy generation of this system constant
My background was biochemistry. "Cancer cells generally show a massive rise in entropy and are exergonic." So cancer cells waste energy and give off heat. Both the heart and the brain use energy inefficiently and give off more heat than other cells at rest. And how/why "measure" entropy? Entropy can't be directly measured, but is derived from other thermodynamic measurements. Sounds like you think bringing a cancer cell's entropy down will stabilize a tumor? No. Cancer is due to damaged DNA.vjrajsingh said:Yes. I'm sorry if I may sound naive but it's only because my background is in biology. I only just started exploring physics.

Non-equilibrium thermodynamics is a branch of physics that studies the behavior of systems that are not in thermodynamic equilibrium. It deals with processes that occur in systems that are constantly changing and not at a steady state.
Equilibrium thermodynamics deals with systems that are in a steady state and do not experience any changes over time. Non-equilibrium thermodynamics, on the other hand, deals with systems that are constantly changing and not at a steady state. It takes into account the flow of energy and matter in and out of the system.
Non-equilibrium thermodynamics has many practical applications in fields such as chemistry, biology, and engineering. It is used to study and understand processes such as chemical reactions, transport phenomena, and biological systems.
Entropy is a measure of the disorder or randomness in a system. Non-equilibrium thermodynamics takes into account the changes in entropy that occur in a system as it moves away from thermodynamic equilibrium. It is an important concept in understanding the behavior of systems that are not at equilibrium.
In theory, yes, non-equilibrium systems can eventually reach a state of thermodynamic equilibrium. However, in practice, this is often not the case as there are many factors that can prevent a system from reaching equilibrium, such as external forces or constant energy input. Non-equilibrium systems can also reach a state of pseudo-equilibrium, where there is a balance between energy input and dissipation.
