H ions . It later helps in conversion of CO2 into glucose . The chemical compound that stores derived from respiration Questions and answers
1 . Organisms that use photosynthesis to produce glucose and other sugar molecules are called phototrophs . All plants are autotrophs (phototrophic ) and some special bacteria- cyanobacteria as well as green algae
2 . Organisms that use aerobic respiration exclusively to produce energy are called obligate aerobes . These organisms are mostly bacteria from different genera which include micrococcus (gram positive cocci pseudomonas (gram negative rods ) and mycobacterium (gram positive bacterium found in dead decaying matter
3 . When oxygen is absent from the cell , an organism meets energy requirements through fermentation where pyruvate is not transferred into mitochondria but remains in the cytoplasm where it is converted into waste through substrate phosphorylation . In skeletal muscle the waste is called lactic acid whereas in yeast it is called alcohol (ethanol -
