idek enzymes and atoms and compounds and stufff Flashcards
What is the pH of a neutral solution?
7 on a 0-14 scale
What is the pH of an acidic solution?
below 7 on a 0-14 scale
What is the pH of a basic (alkaline) solution?
above 7 on a 0-14 scale
What are enzymes?
Ezymes are proteins that speed up a chemical reaction by lowering the activation energy
Why are enzymes important?
without them, Reactions would be too slow to sustain life
What types of things can affect enzymatic activity (the rate of enzyme activity)?
pH, temperature, amount of substrate
What makes up an atom’s nucleus?
protons and neurons
What is found outside the nucleus of an atom?
electrons
Which element is found in organic compounds (that distinguishes it from inorganic compounds)?
CARBON
What is a covalent bond?
electrons are shared
What is an ionic bond?
electrons are transferred
what does DNA stand for
nucleic acid deoxyribonucleic acid
What is the most abundant compound in most living things?
water
How do enzymes affect reactions in living cells?.
Speeds up the chemical reaction by lowering the Activation energy.
What does the term “lock and key” mean when related to the shape of an enzyme and how it fits with a substrate molecule?
fits like a puzzle piece, if shape changes it won’t function. the enzyme is denatured (shape changes). But, there is also induced fit, where it will adjust to the shape
