Question

1. which substrate will the following enzyme react with? next 4 questions: match the function with the correct macromolecule. a. enzymes and structure b. short term energy c. long term energy and cell membrane d. genetic information 16. carbohydrates 17. lipids 18. proteins 19. nulceic acid 20. according to the graph, how are enzymes able to speed up reactions? a. enzymes lower the amount of energy needed to complete the reaction b. enzymes create more heat needed for the reaction c. enzymes create more reactants to complete the reaction d. enzymes increase the amount of energy needed to complete the reaction

Explanation:

1. Enzymes have a specific shape - like a lock - and only react with substrates that fit into their active - site (like a key). The substrate with a complementary shape to the enzyme's active - site will react.
2. Carbohydrates are the main source of short - term energy in the body.
3. Lipids are used for long - term energy storage and are a component of cell membranes.
4. Proteins have many functions including being enzymes and providing structural support.
5. Nucleic acids (DNA and RNA) store and transmit genetic information.
6. Enzymes act as catalysts and lower the activation energy required for a reaction to occur, as shown in the graph.

Answer:

1. The substrate with a complementary shape to the enzyme's active - site (no specific option text given in the question for this part).
2. b. short term energy
3. c. long term energy and cell membrane
4. a. Enzymes and structure
5. d. genetic information
6. a. Enzymes lower the amount of energy needed to complete the reaction
