Q6) The substrate binds the enzyme at active site by temporary bond formation and forms enzyme substrate complex. The formation of enzyme substrate complex reduces the activation energy barrier and proceeds towards product formation. The enzyme and the product is also held by temporary bonds which then separate as a free enzyme and product. therefore the correct option is option C.
Q7) The correct option is Graph B.
The volume of oxygen increases gradually with time and then reaches a stage where the oxygen production doesnot occur further due to the consumption of substrate.

Part A - Overview of enzyme structure and enzymatic reactions Enzymes are large globular proteins. Much of their three dimensional shape is the result of interactions between the R (variable) groups of their amino acids. The active site is the portion of the enzyme that will interact with the substrate the molecule that the enzyme acts upon. The nature and arrangement of amino acids in the active site make each enzyme specific to a substrate and to the reaction it...

Many chemical reactions release energy, while others require energy to happen. These energy changes that occur during chemical reactions are due to changes in bonding between the reactant molecules and product molecules. Breaking bonds between atoms always requires energy, while creating bonds between atoms always releases energy. Analyze each of the two chemical reactions below by calculating the total amount of energy needed to break the bonds in the reactants, the total amount of energy released upon bond formation in...
