The krebs cycle is considered a cycle because?

a. the pyruvic acid never leaves the cytoplasm
b. the citric acid formed remains in the mitochondria for the next acetyl coa
c. carbon dioxide is produced as a waste
d. the reaction can go both ways

Explanation:

MARK ME BRAINY PLZ!(^_^)

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

answer; i believe the correct answer to the above question is ( friction)
