Answer:

There results pointed out that it was possible for organic molecules to be produced under some reducing conditions which are similar to the primitive earth.Specifically they deduced that volcanic eruption occurring simultaneously with the lightning may have been responsible for the production of large quantities of some biological molecules on the early earth.

However, objection was raised to the claim that, NH3 and CH4 used in the experiment were the most abundant gases of primitive earth. Inert Nitrogen and Carbon were the prevalent gases of the early earth,nullifying the authentication of the experiment.Thus their experiment was wrong.

__________ is consumed and __________ is produced in the overall process of cellular respiration.

mixas84 [53]

Answer:

Glucose

Carbondioxide

Explanation:

1.Glucose is phosphorylated and broken down to pyruvate in the process called Glycolysis.

2.The pyruvate is decaboxylated ( loss of Carbon atoms) and enters Kreb cycle where 2 CO2 molecules are lost. 1 C02 from conversation of Citrate to alpha -ketoglutarate , and another 1 CO2 molecule loss from the conversion of Alpha keto glutarate to succinate; for each turn of Kreb cycle.

Therefore 4C02 are produced per one molecule of glucose in cellular respiration as the waste products
