Identify the polynomial.
x3- y3 + z
monomial
binomial
trinomial

Monomials are the the polynomials in which the variable has the highest degree of 1

bionomials are the the polynomials in which the variable has the highest degree of 2

trinomials are the the polynomials in which the variable has the highest degree of 3

so it is a trinomial

Most likely a is the answer - because  you generate   38 atp's but also consume an atp.   each atp gives approx. less than 4 kcal so probably a is the closest answer.

The answer is !
