Enzymes have an individual optimum pH, such as pepsin has a very low optimum pH
true
True
False - sodium and its ion has 11 protons
Correct. Enzymes help to speed up chemical reactions. They may speed them up, costing them some energy, but they are never used up.
Most enzymes are proteins, yes. However, the statement (used some number of years ago) that all enzymes are proteins is false. There are a few (but important) exceptions to that generalization.
The function varies in the same direction as 'x' does. If 'x' is decreasing, then the function is also decreasing.
It is normally regarded as an equation, where y is a function of x. It is possible to regard it as a boolean expression (the equality is true or false).
False . Catalysts can be many things ; enzymes and transition elements and their compounds , for example .So Enzymes are always catalysts but Catalysts are NOT always enzymes .
False; the cosine function is an even function as cos(-x) = -cos(x).
no, every enzyme has a different shape giving it a different job or function
Enzymes have no effect on the overall thermodynamics of a reaction.
The first part of the question is false, and the correct answer is that an even function of minus x equals the function positive x. This follows from the very definition of an even function. The second part of the question is false, because the truth is that the composite function results from taking the function of x within the function g.
False.
Excel has a category called Logical Functions. The IF function is the one of those that most people use and associate with returning True or False values. Other functions also return True or False values. There is a TRUE function and a FALSE function. The OR function and the AND function can be used to return True or False values too. The NOT function can reverse a True or False value, so it also returns True or False.
The answer is "FALSE".
No that is false. Enzymes do NOT increase number of collisions in a chemical reaction.
no they do not
