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.
Salt concentration and the pH! also the temperature and activations and inhibitors affect an enzymes actions
Enzymes can lower the activation energy required for a reaction to occur, making the reaction proceed faster, but they do not affect the equilibrium of the reaction. Enzymes can facilitate both forward and reverse reactions depending on the conditions and the concentration of the reactants and products.
Enzymes control the rate of chemical reactions by lowering the activation energy required for the reaction to occur. This enables reactions to proceed at a faster pace and with more specificity than without enzymes. Enzymes do not change the overall equilibrium of a reaction.
A catalyst. Definition from Pretence Hall Biology: A catalyst is a protein that speeds up the rate of a chemical reaction.
Heat generally speeds up the reaction, while cold will slow it down. The enzymes in the cold are frozen.
Enzymes act as catalysts. They speed up the reaction time.
Enzymes do not affect the equilibrium constant of a reaction. They only speed up the rate at which the reaction reaches equilibrium, but do not change the position of the equilibrium itself.
False. Enzymes do not affect the thermodynamics of a reaction. They only lower the activation energy required for the reaction to proceed, thereby increasing the rate of the reaction without changing the equilibrium constant or overall energetics of the reaction.
By changing the speed of the reaction.
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 affect the speed of reactions predominantly. In some instances in which more than one reaction is possible, enzymes increase the speed of the normally slower reaction enough to make it predominate, while the other possible reaction is effectively suppressed.
activation energy of the reaction.

Enzymes attach to things called substrates to help speed up the reaction. Only certain enzymes match the shape of certain substrates.
Enzymes can lower the activation energy required for a reaction to occur, making the reaction proceed faster, but they do not affect the equilibrium of the reaction. Enzymes can facilitate both forward and reverse reactions depending on the conditions and the concentration of the reactants and products.
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.
