Question

During photosynthesis, plant cells take in water (H2O) and carbon dioxide (CO2) and release oxygen (O2). How is this different from what takes place during aerobic respiration?. . A.During aerobic respiration, cells take in O2 and release CO2, H2O, and ATP.. . B.During aerobic respiration, the mitochondria form CO2 during the process of fermentation.. . C.During aerobic respiration, cells use ATP to convert insulin into glucose and CO2.. . D. During aerobic respiration, O2 is inhaled and CO2 and H2O are exhaled.

Answer 1

A. During aerobic respiration, cells take in O2 (Oxygen is an input of cellular respiration) and release CO2, H2O and ATP.

Cellular respiration equation (THIS IS VERY USEFUL :) ):
C6H12O6 (Glucose) + O2 (Oxygen) = 6CO2 (Carbon dioxide) + 6H2O (water) + 36-38 ATP (energy)

NOTE: Inputs are the things going in, outputs are the things being produced. 

WHY THE OTHER ANSWERS ARE WRONG:
B. Not B because it mentions the process of fermentation which is anaerobic.

C. Not C because insulin has nothing to do with cellular respiration in particular but rather blood glucose level homeostasis 

D. Not D because although it is partially 'correct', the actual wording (inhaled /exhaled) is incorrect as H2O is produced not exhaled. ATP energy is also produced. 

Answer 2

During cellular respiration, the cell utilizes oxygen and release carbon dioxide, water, and energy (ATP).

Further explanation:

Cellular respiration is the process by which energy is produced in the form of ATP (adenosine triphosphate). It occurs in three steps, namely glycolysis, citric acid cycle, and electron transport chain.

1. Glycolysis: in this cycle, the glucose is broken down into smaller substances called pyruvate in the absence of oxygen. It occurs in the cytoplasm of the cell.

2. Citric acid cycle: In the citric acid cycle, the three-carbon pyruvic acid molecules produced during the glycolysis cycle are decarboxylated. The two carbon molecules from acetyl CoA enters the cycle. This reaction occurs in a closed-loop, including eight steps.

3. Electron transport chain: The electron transport chain is a sequence of proteins and other molecules present in the inner membrane of the mitochondria. The transfer of electrons occurs in a chain of the redox reaction. The energy formed during the reaction is stored in the form of a protein gradient. These protein gradients are used in the formation of ATP by the process called chemiosmosis. The combination of ETC and chemiosmosis is called oxidative phosphorylation.

Oxygen and glucose are the reactants. Oxygen enters the body through breathing and glucose is obtained from food. Glucose is the substrate that is broken down into water and carbon dioxide in the presence of oxygen. So, carbon dioxide and water are the products. The metabolism of one molecule of glucose will result in thirty-six to thirty-eight molecules of ATP.
