Competitive inhibitors and how they work?
Inhibitors are substances that alter the activity of enzymes by combining with them in a way that influence the binding of substrate and/or its turnover number. Many inhibitors are substances that structurally resemble their enzyme's substrate but either do not react or react very slowly compared to substrate.There are two kinds of inhibitors: a) competitive inhibitors (those compete directly with a normal substrate for an enzyme-binding site), and b) uncompetitive inhibitors (these bind directly to the enzyme-substrate complex but not to the free enzyme).
What fits with an enzyme to make a reaction occur?
The substrate fits into the enzyme, much the way a key fits in a lock. Sometimes there are other "modulators" that also fit in the enzyme.
What are 3 conditions that can effect the rate of enzymes?
TemperatureAs you increase the temperature of the system in which the enzyme is involved in, the rate of catalysis of the enzyme increases. However, one must make take note that the optimum temperature of the enzyme must not be surpassed because very high temperatures could change the structure of the protein-based enzyme, rendering the enzyme ineffective.Surface Area of the substrateIf you increase the surface area of the substrate, the enzyme will bind to more sites on the substrate and the rate of the reaction will therefore be faster.pHDifferent enzymes work in different environments. One of the factors that determine the state of the environment in which the enzyme operates is its pH. There are enzymes that exhibit optimum rate of catalysis of reactions at in an acidic environment while there are some that exhibit their optimum rate at a basic environment, while yet others only operate in relatively neutral environments.
Give 2 explanations for the fact that only certain substrate molecules will fit into this part of the enzyme molecule?
A substrate molecule will only fit into the active site if it is a complimentary shape. Also the amino acids that make up an enzyme have positively and negatively charged chemical groups so in orderr for a substrate to fit its active site any electrical charges on the substrate molecule must not be repelled by like charges on the enzyme so the charged groups on the enzyme molecule and substrate molecule must attract one another
How does the cell know which enzyme to make and how to make it?
The cell follows genetic instructions encoded in the DNA to determine which enzyme to make. This process involves gene expression, where specific genes are transcribed into messenger RNA (mRNA) and then the mRNA is translated into the corresponding enzyme. Ribosomes in the cell read the mRNA sequence and assemble the amino acids into the specific enzyme structure based on the genetic code.
How does enzyme concentration affects the rate of enzyme action?
it slows down the reaction time of the enzyme because there are too many substrates bumping into each other and make it harder for them to bind to the enzymes.
What helps an enzyme to bind to a specific active site?
What? Enzyme doent look for another enzmes active site! it just look for its substrate to bind at in its active site! This will in turn make it to form any by products or convert it from the actual state!
Molecule that binds to an enzyme?
A molecule that binds to an enzyme is usually referred to as a substrate. Substrates are the molecules on which enzymes act to catalyze a biochemical reaction. Upon binding to the enzyme's active site, substrates undergo a chemical transformation to form products.

Why do enzyme molecules change shape at high temperatures?
The rate of enzyme reactions is affected by temperature. All enzymes have an optimum temperature range in which they work most efficiently. An enzyme is most active at its optimum temperature. A temperature rise beyond this point reduces enzyme activity till it completely stops. This happens because the enzymes structure has changed, (often a loss of the correct folding of the molecule) and it's irreversiable. The change of the structe makes the enzyme become useless because it can't bind to subrates to make chemical reactions.
What do bookbinders do?
they bind, repair, and make books.
What Unwinds the DNA strand and breaks the hydrogen bonds between nucleotides in preparation for replication?
The initiation complex makes a small gap for a helicase enzyme to bind. It is the helicase the 'undwinds' the DNA for most of replication. In E. coli, for example, DnaA protein binds DNA to make a small gap between the two DNA strands, where DnaB enzyme (a helicase) can bind to the lagging strand (the one that is copied in fragments). From there, DnaB unwinds the DNA ahead of the polymerase enzyme.
What happens to bonds during the enzyme substrate complex?
Depends on which enzyme and which substrate, but it goes like this with any of them. Let's take amylum (starch, the substrate) and amylase (saliva, the enzyme). A enzyme binds itself to a substrate, and forms a enzyme substrate complex. The catalyzing powers of the enzyme makes the vulnerable connections in the amylum weak to make it break, which creates product(s) out of the amylum.

How do bees make honey from nectar?
They have a secrete enzyme in there mouth that when they they collect nectar and mix it with the enzyme it makes honey.
What is the enzyme that bees use to make honey?
Invertase
What enzyme plays a role in replication?
the make food
