Biology: Enzymes and Biochemical Reactions

Metabolism

all of the chemical reactions within each cell at an organism, provides energy for life's process, and create key molecules

Chemical Reactions

the breaking and forming of bonds between different substances during chemical changes

Catabolic

Breaks down larger molecules into simplier compounds

Anabolic

builds larger molecules from smaller ones

Exergonic

a release in energy in Catobolic

Activation energy

the amount of energy needed to make chemical reaction start

Reactants(substrate)

substances that are changed during a chemical reaction

Products

substances that are made by a chemical reaction

Endothermic

energy release, Catabolic, and an example is cellular respiration

Exothermic

energy mass in, anabolic, and photosynthesis

Enzymes

mostly proteins that speed up biochemical reactions by lowering the activation energy. A protein catalysts

Catalysts

substances that speed up reactions without being permanently altered

Lock and Key Hypothesis

1. Proteins
2. Not change in a reaction
3. Can be used over and over again
4. Specific

Denaturation

enzymes active site gets deformed and loses its specific shape

Denaturation is caused by?

Extreme changes in pH, temperature, ion strength, and solubility

5 Ways to change the rate of chemical reaction

temperature, pH, substrate concentration, catalysts, and competitive inhibitor.

Temperature

increasing temperature increases the rate of the reaction

ph

how acidic a solution is

substrate concentration

The higher the amount of substrate, the faster the reaction

Competitive Inhibitor

slow down reaction

endergonic

builds larger molecule from smaller ones in Anabolic
