NEET Questions / Botany / Photosynthesis in Higher Plants / Photorespiration And C4-Cycle
In photorespiration, RuBP is converted to:
PGA and phosphoglycolate
Two molecules of PGA
Two molecules of phosphoglycolate
PGA and oxaloacetate
Which organelle is involved in the salvage pathway of photorespiration?
Chloroplast
Mitochondrion
Peroxisome
Golgi apparatus
During photorespiration, RuBisCO binds to which molecule instead of CO2?
Oxygen
Nitrogen
Hydrogen
Water
Which type of plants primarily utilize the C4 pathway?
Plants in hot, dry environments
Plants in cool, shaded environments
Aquatic plants
All plants
The first stable product of the C4 pathway is:
Oxaloacetate (OAA)
Pyruvate
3-phosphoglycerate (3-PGA)
Ribulose-1,5-bisphosphate (RuBP)
Which enzyme is responsible for the initial carboxylation in C4 plants?
PEP carboxylase
RuBisCO
Kinase
Dehydrogenase
In which cell type does the Calvin cycle occur in C4 plants?
Bundle sheath cells
Mesophyll cells
Epidermal cells
Guard cells
The primary distinction between and plants lies in their:
initial product of fixation
ability to grow in hot and dry climates
utilization of light energy
requirement for water
The first stable compound formed during carbon fixation differentiates and plants. In plants, this compound is:
3-PGA
Oxaloacetate
RuBP
Glucose
