Would photosynthesis be considered an anabolic process?
Of course photosynthesis is an anabolic process,here glucose and oxygen is synthesized from co2 and water.
photosynthesis is an anabolic process is catalyzed by?
Chlorophyll and a list of specific enzymes, like Ribulose-DiPhosphate carboxylase.
Why does a biological process that occurs without an input of energy have to increase universal entropy?
My Biology book says
“For a process to occur spontaneously, it must increase the entropy of the universe”
If you put two monosaccharides (or any other monomer, for that matter) and a water molecule in a closed environment, you will get a polymer of some sort. That is an anabolic process, one that increases the order of the universe.
I’m sorry if this is a silly question. Any help is greatly appreciated.
If you’re thinking of dehydrating two monosaccharides, for example, you’d get two molecules out (disaccharide + water) for the two monosaccharides you put in, so it’s not obvious that you’ve increased the order of the system, and I’m pretty sure that hydrolysis is spontaneous and not the reverse.
Look at it this way: a rxn is spontaneous if its Gibbs free energy dG = dH – TdS 0, then the entropy of the system increases. If a process is spontaneous and dH 0. Either way, the entropy of the universe dS(system) + dS(surroundings) > 0.
Now that’s not really a rigorous demonstration, but it will be if you partition the universe into system and surroundings, and account for the change in the entropy of the surroundings due to heat into or out of the system. The point of Gibbs work was that you can combine energy and entropy into an expression for useful work, that useful work can be extracted in moving from one state to another with lower Gibbs free energy, and that the second law places the same constraint on useful work in a chemical system as it does in a purely mechanical system.
Really though you’ll want a thermo book, or maybe a chemical thermo book, to pursue this. This topic terrifies most chemists and all biologists, and you likely won’t get anything but gibberish from them as they parrot whatever was in *their* biology books.
Is growth catabolic to anabolic process or anabolic to catabolic process.. if so y?
Growth is an Anabolic process.
Anabolic processes tend toward “building up” organs and tissues. These processes produce growth and differentiation of cells and increase in body size, a process that involves synthesis of complex molecules. Examples of anabolic processes include the growth and mineralization of bone and increases in muscle mass.
Is the process of synthesis of glycogen anabolic or catabolic?
Anabolic, and the word ‘synthesis’ also gives it away….in addition, glycogen is a polymer of glucose
So….it’s anabolic (building a larger molecule from smaller component molecules)
