The right option is; c. can be used and consumed without risk
The defining characteristic of potable water is that it can be used and consumed without risk.
Potable water is the water that is considered safe for human consumption without risk of health problems. Potable water meets drinking water quality standards in terms of physical, chemical and microbiological parameters. Potable water has been treated and it is assumed to be considerately free of harmful pathogens such as bacteria and contaminants.
Answer:Enzymes that makes redox reactions possible in a biochemical process includes those that help to catalyze the transfer of electrons, atoms, or functional groups.
Explanation:
Here are some class categories of these enzymes and their roles ;
• Oxidoreductases - Transfer of electrons (hydride ions or H atoms)
• Transferases - Group- transfer reactions
• Hydrolases - Hydrolysis reactions (transfer of functional groups to water)
• Lyases - Addition of groups to double bonds, or formation of double bonds by removal of groups Transfer of groups within molecules to yield isomeric forms
• Isomerases - Formation of C-C, C-S, C--0, and C-N bonds by condensation reactions coupled to ATP cleavage
The above are however classified, given code numbers, and assigned names according to the type of transfer reaction, the group donor, and the group acceptor.
C seems like the correct answer
