Answer:
The overall chemical reaction of cellular respiration converts one six-carbon molecule of glucose and six molecules of oxygen into six molecules of carbon dioxide and six molecules of water. ... So the carbons in the glucose become oxidized, and the oxygens become reduced.

Explanation:
Metabolic pathways involve all the chemical processes takes place in the enviornment or in an organisms.The metabolic pathways are controlled through the catalytic activities of enzymes.
The availability of enzyme is regulated by substrate and cofactors present in enzyme and enzyme activity is commonly regulated via covalent modification.
Enzymes are highly selective in nature and bind to a specific substarte only. The active site in enzyme binds with the substrate to form enzyme substrate complex. Coactors assist the enzyme activity, without cofactor enzyme can not perform its activity.
Hence enzyme availibility is regulated by substrate and cofactors regulates.
Covalent modifications regulates activity of enzyme as it involves addition and removal of chemical group to synthesis required protein. It can change the chemical properties of the site by targeting one or multiple amino acid.
Thus the correct answer is a) substrate and cofactors b) covalent modification
Structure and Function is my answer
Answer:
the frog and cricket are eaten by snake and soil bacteria all dead organisms are eaten by soil bacteria.
The sun is the energy source for grass which is in turn an energy source for crickets and soil bactiera. Snakes and frogs eat the crickets and snakes also eat the frogs. When all the animals including grass die then will get eaten by the soil bacteria.
