Which statement describes how enzymes and substrates are related? the enzyme influences the speed of change from substrate to product. enzymes are released as substrates in a chemical reaction. an enzyme is a special kind of substrate in a chemical reaction. substrates combine with enzymes to form reactants.
Correct A). The enzyme influences the speed of change from substrate to product
The enzymes are the biological catalyst that speed up the rate of chemical reactions by decreasing the activation energy of the reaction pathway.
They increase the speed of change of substrate to the product and it remains unchanged in the reaction. Hence, it can be used again and again.
Enzymes are highly specific in nature, only a specific substrate binds to the enzyme's active site. Hence, a particular enzyme is required to catalyze a reaction.
Catalysis is defined as the acceleration the of the rate of a chemical reaction, enzymes are natural catalysts that can make more efficient, faster reactions by using less energy and generating less waste.
I hope you find this information useful and interesting! Good luck!
Decrease the activation energy
For a chemical reaction to occur, the activation energy (the transition energy to move up from the reactant state) must be overcome. Enzymes lowers this activation energy thus speeding up the rate at which reaction occurs
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy. (www.biology.arizona.edu/biochemistry/problem_sets/energy_enzymes.../01t.html)
Hope this helps
Yes the answer is A. got it correct.
Give that man a cookie!
Enzymes are biological catalysts. That means they increase the speed of change from substrate to product. Enzymes remain unchanged during the reaction they catalyze.
Through the process of elimination:
B) is eliminated because enzymes are not released as substrates. These two are different molecules in the reaction.
C) An enzyme is not special kind of substrate.
D) Substrates combine with enzymes not to form reactants, but to form products.
