Anaerobic respiration is also called :
restoration
fragmentation
multiplication
fermentation
D.
fermentation
Anaerobic respiration is respiration using electron acceptors other than molecular oxygen (O2).
After glycolysis, if oxygen is absent (anaerobic respiration), the pyruvic acid forms ethyl alcohol (C2H5OH) and carbon dioxide (CO2) without the help of any cell organelle. This anaerobic process is called fermentation.
The plants respond to photoperiods due to the presence of :
enzymes
stomata
phytochromes
phytohormones
A person breathing normally at rest, takes in and expels approximately half a litre of air during each respiratory cycle. This is called :
tidal volume
vital capacity
inspiratory reserve volume
expiratory reserve volume
Mesophyll cells, which liberate malic acid at night time, are of :
C4 - plants
C3 - plants
C2 - plants
C1 - plants
Asthma is caused due to :
infection of lungs
infection of trachea
bleeding into pleural cavity
spasm in bronchial muscles
The name of process of aerobic respiration, in which energy is provided in steps in electron transport chain, is :
EMP-pathway
decarboxylation
photophosphorylation
oxidative phosphorylation
The first heart sound is produced when :
diastole begins
semilunar valve close quickly
interventricular pressure decreases
bicuspid and tricuspid valve close quickly
