Which of the following is included in exhaled air?
RRB NTPC (Stage-I)
16/04/2016 (Shift-I)
2016
✓ Answer:DNitrogen
The source key selects nitrogen. However, exhaled air also contains water vapour, making both C and D valid under the wording provided.
842
In the human body, the respiratory pigment is _____.
RRB Group-D
27/09/2018 (Shift-III)
2018
✓ Answer:BHaemoglobin
Haemoglobin in red blood cells binds oxygen reversibly and transports respiratory gases.
843
During each breathing cycle, when air is taken in and thrown out, the lungs always contain some amount of air so that there is sufficient time for oxygen to be absorbed and carbon dioxide to be released. What is this amount of air called?
RRB Group-D
05/09/2022 (Shift-II)
2022
✓ Answer:DResidual volume
The source answer is residual volume. Strictly, residual volume is the air remaining after maximal forced expiration; air remaining after normal expiration is functional residual capacity.
844
Inflammation of the mucous membrane is called _____.
RRB NTPC (Stage-I)
19/04/2016 (Shift-I)
2016
✓ Answer:ABronchitis
The intended answer is bronchitis, meaning inflammation of the lining of the bronchi. The question is incomplete because it does not specify which mucous membrane.
845
Which one of the following combines with O₂ to provide energy in our body?
RRB Group-D
05/11/2018 (Shift-III)
2018
✓ Answer:DGlucose
The intended answer is glucose, the substrate used in the standard equation for aerobic respiration. Other fuels can also be oxidised to provide energy.
846
Breathing is harder at high altitudes compared to sea level because _____.
RRB Group-D
22/09/2022 (Shift-III)
2022
✓ Answer:DThe atmosphere is less dense at high altitudes
Atmospheric pressure and oxygen partial pressure decrease with altitude, reducing the oxygen available with each breath.
847
When respiration takes place in the absence of oxygen, it is called _____ respiration.
RRB NTPC (Stage-I)
23/01/2021 (Shift-I)
2021
✓ Answer:BAnaerobic
Anaerobic respiration or fermentation releases energy from substrates without using oxygen, as described in school-level terminology.
848
Anaerobic respiration occurs in the absence of _____.
RRB Group-D
30/10/2018 (Shift-II)
2018
✓ Answer:AOxygen
Anaerobic energy-releasing pathways operate without oxygen.
849
What is the role of cilia in the respiratory tract?
RRB Group-D
22/09/2022 (Shift-III)
2022
✓ Answer:BCilia sweep mucus from the lungs and airway towards the nose.
Cilia move mucus and trapped particles along the airways toward the throat for removal. The source describes this as movement towards the nose.
850
In the respiration process, complex organic compounds such as glucose are broken down to provide energy in the form of _____.
RRB NTPC (Stage-I)
09/01/2021 (Shift-I)
2021
✓ Answer:BATP
Energy released during cellular respiration is captured in ATP, adenosine triphosphate, which powers cellular activities.
