enzymes CO,
(3) enzymes Og Coz glucose
(4) glucose

(2)
O2
CO2

Answer 1

Answer:

Cellular respiration is the biological process that occurs in both plants and animals.

Option (row )2 is the right one that fits in the equation.

A + B → D + ATP + H2O (In the presence of C)

A. glucose

B. O2

C. Enzyme

D. CO2

Glucose + O2 → CO2 + ATP + H2O (in the presence of Enzyme)

Cellular respiration is a reverse process of photosynthesis. During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose.

Answer 2

Answer: B

A-Glucose

B-Oxygen

C- Enzyme

D- CO2

Complete Equation

Glucose + Oxygen → ATP +  C02  + H20.

                            enzyme

Explanation:

This  represented the chemical pathway of Cellular respiration. it is the process of breaking down glucose in the cytoplasm to pyruvate in presence of enzymes(hexokinase, phosphorfructokinase) the process is called  Glycolysis,

The use of the pyruvate as acetyl Co A combined with oxaloacetate to generate ATP, and produce C02 and H20 vapour as by-products in a pathway called Kreb-Cycle. H+ are removed by Coenzymes NADH+ and FADH+

The NADH+ and FADH+  are transferred  to the mitochondria matrix , where Hydrogen  is split to H+ and e-for ECT,  The e- forms the electron transport chain, and while the H+ is pumped by PMF across the mitochondria intramembrane to generate energy  from electrochemical gradients which is needed  for ATPs synthesis, by ATPase synthase. Oxygen is the final oxygen acceptor.    

Thus option B is the answer.
