Question

what is activation energy,carbohydrate and dehydration synthesis

Answer 1

activation energy: even if a process is spontaneous, it requires a certain amount of initial energy (activation energy) to get it going, glucose metabolism in glycolysis and aerobic respiration is a perfect example. This diagram shows a good representation of this (Ea is activation energy): http://bio1151.nicerweb.com/Locked/media/ch08/08_14ExergonicReaction.jpg

carbohydrate: like the name suggests, these are molecules (one of the 4 macromolecules) that contain Carbon, Hydrogen, and Oxygen (-hydrate). The simple carbohydrates in non-ring form have the formula CnH2nOn (for every carbon there is 2 hydrogen and 1 oxygen). Biologically these molecules are used for energy (i.e. glucose, glycogen) and structure (i.e. cellulose and chitin).

Dehydration reaction: a common reaction in biology (i.e. all macromolecules) that binds two monomers together, while removing a water molecule in the process. For example two amino acids come together, the N-terminus of one amino acid looses an H and the the C-terminus of the other amino acid looses an -OH. The two amino acids bind, forming a peptide bond, and remove one water molecule... in other words De-hydration reaction (loose water to form a bond). The opposite of this hydrolysis (put water in to lyse or break apart).

Hope this helps!

it does thanks

tag me with '@neuronerd' if you have any more questions that I could answer

Answer 5

k but how im new to this

Answer 6

Ah totally cool: literally just type the symbol @ and then my (or any one else's) username. If you're a fan of that person, it will suggest names after typing in '@'
