Answer : An atom with 7 protons, 6 neutrons,
and 7 electrons has an atomic mass of 13 amu.
Explanation:
As we are give that,
Number of protons
7
Number of electrons =7
Number of neutrons =6
As we know that,
Atomic number =Number of protons = Number
of electrons =7
Atomic mass = Number of neutrons + Atomic
number
Atomic mass = 6 + 7 = 13 amu
Therefore, the atomic mass is, 13 amu
Answer:
Enzymes attached with the body of substrate and speedup the reaction.
Explanation:
Enzymes attached with the body of substrate i. e. starch and increase the speed of break down and when the substrate is broken down, these enzymes detached from the substrate. Enzymes are the chemical substances present in the body of organism which helps to speedup the process of digestion. The digestion of starch starts from the mouth with the help of salivary enzyme and this starch is converted into smaller molecules which can be absorbed by the cells.
