Enzymes are not used in the reaction so usually the enzyme will sort of reset and be ready to use in another reaction . this is because enzymes are proteins and their shape is what they use in a chemical reaction so when the reaction is done the product is released (the reaction) and the enzyme can relax and go back to its normal shape
Answer:
The minimum number of nucleotides per codon necessary to specify all 20 amino acids that are found in proteins is <u>3</u>
Explanation:
There are four nucleic acids in the RNA, adenine uracil, guanine, cytosine. Each of them combines in groups of three to give the different amino acids. In total, there are 64 different combinations of nucleic acids that codify the 20 amino acids that we need for our vital functions.
Answer:
All of the choices are correct.
Explanation:
- When a substance emits light which is not a result of heat, then such a spontaneous emission fo light is known as luminescence.
- Several chemical reactions or electrical energy can lead to the production of luminescence by organisms.
- The enzyme that is responsible for the production of bioluminescence by the organism is luciferase and it is capable of producing luminescence by catalyzing oxido-reductive processes.
- Luminescence is also produced in bacteria, and it is often controlled by the process of quorum sensing.
Explanation:
Biologists attempt to answer questions about the living world.
Metabolism, respiration and digestion are all complex chemical processes involving many steps, happening in 3 dimensional space within cells. Metabolism is the breaking of bonds within food molecules (like sugar) to harness energy for cellular work; respiration involves moving oxygen and carbon dioxide gases between cells to facilitate cellular metabolism and digestion involves breaking down food macro structures into smaller units suitable for metabolism.
So the answer is D - each of the three process involve multiple chemical reactions.
