What is the following biology question?

Question

______________ are biological catalysts synthesized by living organisms.

And, what does this mean?

Answer 1

Enzymes

A catalyst may be used to speed up a reaction favoring the end products, and reduce the "activation energy" required to cause the desired reaction to happen.

Having the reagents react first with the catalyst makes all the difference.

After the reaction takes place, the products are released, and the catalyst is left with no net change -- free to catalyze again!

Answer 2

Definitely enzymes, enzymes speed up reactions by providing an alternative energy pathway for the reaction to occur in, and also lower the activation energy for a reaction. This means that the reaction can occur with less energy input. Synthesized means 'made', in that the cells in our body produce enzymes via protein synthesis. An enzyme is a protein, as it consists of amino acids, and these are synthesised at ribosomes.

Answer 3

The answer is enzymes, they are biological catalysts which are used to speed up a reaction without using themselves up they usually make a enzyme-substrate complex called an intermediate and give the enzyme and a product in the end.

Answer 4

Definately enzymes.

Biological catalysts speed up the rate of reaction of biochemical processes in the body - otherwise it will take forever and an organism cannot survive. Enzymes themselves are proteins with specifically shaped active sites, enabling them to catalyse specific reactions.

Answer 5

As far as I know if you take science related courses in any university, most of them or all of them requires you to take at least Pmath 11 to get into universities. If the school wants you to take math, then it must be important that you take it. Math is important in biology. Lets put it this way, when doctors have to open your head because some metal got through, they don't just cut through it, they have to analyze first how much of your head should be cut open. The smaller cut they make the less danger it would do to you. If you don't like math very much, talk to your counsellor and ask them for some advice. If you are really sure you like biology i think you might just have to suffer a little. Studying the human body is pretty challenging and exciting, if you treat math to be as important as biolody, math can be pretty challenging too.

Answer 6

Enzymes. A catalyst is a chemical that speeds up a chemical reaction but is not broken down by the reaction. Enzymes fit that description since they lower the activation energy of a reaction speeding it up; and it is not destroyed by the reaction and can be reused.

Answer 7

Definitely ENZYMES
They are known as biocatalysts, which are involved in the catalysis of biological reactions occurring inside living cells, without undergoing any change as a result of the reaction.

Answer 8

Enzymes:

They are proteins which are produced by protein synthesis.

Enzymes speed up a reaction. They speed up a reaction by lowering the energy of activation time.

Answer 9

could be "enzymes". These are produced by living organisms to catalyse reactions. This means, the enzyme is produced, and the reaction that is to be taken place is activated (catalysed) by the enzyme being present. Hope this helps

Answer 10

"Vitamins" are among the catalysts that facilitate important reactions in turning food into energy. They take the intermediate products from a reaction and make it easy for the reaction to proceed to the next step. If the body does not have enough of them they are a limiting factor in those reactions.
