Detailed explanation-1: -Examples of coenzymes: nicotineamideadenine dinucleotide (NAD), nicotineamide adenine dinucelotide phosphate (NADP), and flavin adenine dinucleotide (FAD). These three coenzymes are involved in oxidation or hydrogen transfer.
Detailed explanation-2: -Coenzymes bind to the enzyme and assist in enzyme activity. They can bind and react with many different enzymes, so they’re not specific to a particular enzyme. They help enzymes change starting elements (substrates) into their final version (products).
Detailed explanation-3: -An inactive enzyme without the cofactor is called an apoenzyme, while the complete enzyme with cofactor is called a holoenzyme.
Detailed explanation-4: -Temperature: Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working. pH: Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity.
