Test: The Respiratory Balance Sheet Amphibolic Pathway & Respiratory Quotient (July 7) - Question 1

The overall goal of glycolysis, Krebs cycle and electron transport system is the formation of

Test: The Respiratory Balance Sheet Amphibolic Pathway & Respiratory Quotient (July 7) - Question 2

When fats are the respiratory substrate, the value of RQ would be​

Detailed Solution for Test: The Respiratory Balance Sheet Amphibolic Pathway & Respiratory Quotient (July 7) - Question 2

The respiratory quotient (RQ) is used in calculations of basal metabolic rate (BMR). It is the ratio of the volume of carbon dioxide produced by the body to the volume of oxygen consumed by the body in respiration over a period of time. It depends on the type of respiratory substrate used during respiration. RQ of fat is about 0.7. RQ of carbohydrate is 1. RQ of organic acids is above 1. RQ of protein is 0.9. RQ value gives information about the source of energy an animal is using.
Thus, the correct answer is option A.

Test: The Respiratory Balance Sheet Amphibolic Pathway & Respiratory Quotient (July 7) - Question 3

Out of 38 ATP molecules produced per molecule of glucose, 32 ATP molecules are formed from NADH/FADH2 in the​

Detailed Solution for Test: The Respiratory Balance Sheet Amphibolic Pathway & Respiratory Quotient (July 7) - Question 3

 

The electron transport chain along with oxidative phosphorylation involves the synthesis of energy-rich ATP molecules with the help of energy released during the oxidation of reduced coenzymes (NADH2 and FADH2) formed during glycolysis and the Krebs cycle. A total of 10 NADH2 and 2 FADHmolecules are produced during aerobic respiration. They help in the formation of 32 ATP molecules.

Test: The Respiratory Balance Sheet Amphibolic Pathway & Respiratory Quotient (July 7) - Question 4

Respiratory substrates are the organic substances which are ________ during respiration to liberate energy.

Detailed Solution for Test: The Respiratory Balance Sheet Amphibolic Pathway & Respiratory Quotient (July 7) - Question 4

Respiration is an oxidative process in which repiratory substrates are oxidised to liberate energy inside the living cells. The common respiratory substrates are carbohydrates, proteins, fats and organic acids. The most common respiratory substrates are carbohydrates, proteins, fats and organic acids. The most common respiratory substrate is glucose.

Test: The Respiratory Balance Sheet Amphibolic Pathway & Respiratory Quotient (July 7) - Question 5

Respiratory quotient may be represented as

Detailed Solution for Test: The Respiratory Balance Sheet Amphibolic Pathway & Respiratory Quotient (July 7) - Question 5

During aerobic respiration O2 is consumed and CO2 is released. The ratio of the volume of CO2 evolved to the volume of O2 consumed in respiration over a period of time is called as respiratory quotient (RQ) or respiratory ratio.

The respiratory quotient depends upon the type of respiratory substrate used during respiration.

(i) When carbohydrates are used as substrate and are completely oxidized the RQ will be 1, because equal amounts of CO2 and O2 are evolved and consumed respectively.

(ii) When proteins are respiratory substrates, the ratio would be about 0.9.

Test: The Respiratory Balance Sheet Amphibolic Pathway & Respiratory Quotient (July 7) - Question 6

If the volume of CO2​ liberated during respiration is more than the volume of O2​ used the respiratory substances will be

Detailed Solution for Test: The Respiratory Balance Sheet Amphibolic Pathway & Respiratory Quotient (July 7) - Question 6

RQ slightly more than unity is found when organic acids are broken down as respiratory substrates under aerobic conditions, e.g., for breakdown of oxalic acid,

Test: The Respiratory Balance Sheet Amphibolic Pathway & Respiratory Quotient (July 7) - Question 7

Value of R.Q. in succulents is _________.

Detailed Solution for Test: The Respiratory Balance Sheet Amphibolic Pathway & Respiratory Quotient (July 7) - Question 7

Succulents do not evolve carbon dioxide during the night (when their stomata are open) as the same is in carbon fixation. They also change carbohydrates to organic acids which utilise oxygen but do not evolve carbon dioxide.

Test: The Respiratory Balance Sheet Amphibolic Pathway & Respiratory Quotient (July 7) - Question 8

RQ in anaerobic respiration is?

Detailed Solution for Test: The Respiratory Balance Sheet Amphibolic Pathway & Respiratory Quotient (July 7) - Question 8

In anaerobic respiration, there is no consumption of oxygen and carbon dioxide is produced in most of the cases. Therefore, respiratory quotient is infinity. Carb the usual substarte.

Test: The Respiratory Balance Sheet Amphibolic Pathway & Respiratory Quotient (July 7) - Question 9

Instantaneous source of energy is _______.

Detailed Solution for Test: The Respiratory Balance Sheet Amphibolic Pathway & Respiratory Quotient (July 7) - Question 9

Glucose is a monomer that after ingestion, does not gets digested and directly gets absorbed and converted into energy. Therefore, glucose is an instantaneous source of energy.
Protein, fats, and nucleic acid don't get directly converted into energy. So, they are not the instantaneous source of energy. 

Test: The Respiratory Balance Sheet Amphibolic Pathway & Respiratory Quotient (July 7) - Question 10

Complete the following biochemical equation of respiration and select the correct answer.

Detailed Solution for Test: The Respiratory Balance Sheet Amphibolic Pathway & Respiratory Quotient (July 7) - Question 10

Aerobic respiration is a chemical reaction in which glucose gets oxidise and converted into carbon dioxide and water. The following is the balanced chemical reaction -
C6H12O6 ​+ 6O2 ​→ 6CO2 ​+ 6H2O + Energy.
