There's no set answer to how long the battery charge will last - it all depends on what you're doing with the tablet. Actions such as connecting to the internet, playing games or movies and other complex tasks will consume power faster than more simple tasks like writing emails or reading an ebook.
THE EFFECT OF CHANGING CONDITIONS IN ENZYME CATALYSIS This page looks at the effect of changing substrate concentration, temperature and pH on reactions involving enzymes. It follows on from a page describing in simple terms how enzymes function as catalysts.
Protein molecules that act as catalysts in biochemical reactions Enzymes allow many chemical reactions to occur within the homeostasis constraints of a living system.Enzymes function as organic catalysts. A catalyst is a chemical involved in, but not changed by, a chemical reaction.Many enzymes function by lowering the activation energy of reactions.nzymes function as organic catalysts.
