Describe how electrons are arranged in a carbon atom including the valence electrons. then, explain what type of bonds carbon will form with other atoms and why they form (why does carbon want to form bonds with other atoms)? finally, based on this information, explain why carbon forms the backbone of all molecules that comprise living cells.

the organisms are not adapted to live in some communities or habitats.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
