Select the correct statements about glycolysis.
a. two glucose molecules are needed to initiate glycolysis.
b. major products of glycolysis include pyruvate, atp , and nadh .
c. glycolysis is the process by which glucose is converted to two molecules of pyruvate.
d. glycolysis occurs in the mitochondria of the cell. glycolysis is an aerobic process.

B and C

Explanation:

Option A is wrong because only one glucose molecule is needed to initiate glycolysis

Option B is correct the major product of Glycolysis is 2 molecules Pyruvate, 4 ATP and 2 NADH are also produced at the end of glycolysis.

Option C is correct Glycolysis is the process by which glucose is converted to two molecules of PYRUVATE.

Option D is wrong because Glycolysis occurs in the cytoplasm of the cell.

Option E is also wrong because Glycolysis is an ANAEROBIC process

Answer is B and C

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
