The reactions of glycolysis occur in the cell's ________; the reactions of the citric acid cycle occur in the ________.
Reil [10]

Answer:

The reactions of glycolysis occur in the cell's <u>cytoplasm</u>; the reactions of the citric acid cycle occur in the <u>mitochondria</u>.

Explanation:

<em><u>Explanations of some terms</u></em>

Glycolysis

Glycolysis takes place in the cytosol of the cell's cytoplasm. Glycolysis starts when glucose diffuses into a cell through the plasma membrane down its concentration gradient. Glycolysis is a metabolic pathway present in all organisms: from yeast to mammals that involves the oxidation of glucose molecules, the single most important organic fuel in plants, and animals to pyruvate with the generation of ATP (Adenosine triphosphate) and NADH (nicotinamide adenine dinucleotide + hydrogen)

Citric acid cycle

Citric acid cycle also known as the Krebs cycle plays a major role in the process of energy production and biosynthesis as it oxidizes glucose derivatives, fatty acids and amino acids to carbon dioxide.

n200080 [17]

Answer:

3 moles

Explanation:

This question is on stoichiometry of reactions

Given

2H₂ +O₂⇒2H₂O-------------------the equation is balanced

<u>Find the mole ratio</u>

2H₂ +O₂⇒2H₂O

2        1       2

O:H = 2:1---------------------------------every mole of hydrogen requires two moles of oxygen to complety react

Thus given 6 moles of hydrogen;

O:H

?:6

=6/2=3 moles

zimovet [89]

Answer:

See below

Explanation:

The glycosidic bond forms between the carbon atom on the glucose molecule and the nitrogen atom present on the nitrogenous base. A diagram has been attached to show this particular bond. There is also a phosphate molecule bonded on the sugar molecule at the other end.
