Photorespiration in C3 -plants starts from :
glycine
glycerate
phosphoglycolate
phosphoglycerate
C.
phosphoglycolate
Photorespiration in C3 -plants starts from phosphoglycolate. Phosphoglycolate is formed in chloroplast which represents the source of carbon dioxide released in photorespiration. Its phosphate group is first hydrolyzed away by a specific phosphatase found in chloroplasts of C3 -plants releasing Pi and glycolic acid. The glycolate then moves out of chloroplasts into the adjacent peroxisomes.
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
The plants respond to photoperiods due to the presence of :
enzymes
stomata
phytochromes
phytohormones
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
Asthma is caused due to :
infection of lungs
infection of trachea
bleeding into pleural cavity
spasm in bronchial muscles
The first heart sound is produced when :
diastole begins
semilunar valve close quickly
interventricular pressure decreases
bicuspid and tricuspid valve close quickly
