Temperature, presence of acid, presence of base as all three can cause denaturation of enzyme.
Amount of sun, amount of clouds and amount of moisture in the air are 3 examples of things that could affect temperature.
enzymes
hii
Enzymes fasten chemical reactions, inhibitors blocks the enzymes and they will not accelerate the reaction.
Wind, deflection from land, temperature differences between layers of cold and warm water.
Salt concentration and the pH! also the temperature and activations and inhibitors affect an enzymes actions
Enzymes act as catalysts. They speed up the reaction time.
specificity, temp, ph, inhibitors
Substrate concentration will affect enzymes because substrates are specific to enzymes. The pH will affect enzymes because certain enzymes will work better in certain pH levels.
Water, metabolic wastes, and enzymes
Enzymes lower the activation energy (or free energy of activation for the very scientific) of the chemical reactions they catalyse. The enzymes can make a reaction proceed much more quickly than it otherwise would by astronomical figures, e.g. 109 times! Enzymes don't affect the equilibrium position, but they do affect the rate.
It disrupts an enzymes shape and structure.
enzymes as described by my bio teacher do "chores" in the body, when something needs to be done, our body uses enzymes. you can recognize enzymes by looking for the suffix (ase) at the end of a word. An example of an enzyme and its use is Helicase, which unwinds DNA strands at the beginning of transcription.
Enzymes lower the activation energy required for reactions to occur
enzymes are never consumed in a chemical reaction, therefore the answer to your question is that enzymes that affect the speed of a chemical reaction without being consumed are indeed called enzymes.
Enzymes have no effect on the overall thermodynamics of a reaction.
pH, temperature, concentration of enzyme, substrate concentration, etc
