metabolic reactions which need energy

1. MOVEMENT
• Movement of cilia,flagella
• Muscle contraction
• Movement of chromosomes

2. MAINTAIN CONSTANT BODY TEMPERATURE
Endotherms need energy to keep body
temperature
stable so that their enzymes function effectively

3. ANABOLIC PROCESSES
Formation of large,complex molecules from
small
simpler molecules

4. ACTIVE TRANSPORT
Energy is needed to move molecules and ions
across
cell membrane against concentration gradient

5. BIOLUMINESCENCE
Organisms which convert chemical energy into
light.

6. SECRETION
Packaging and transport of secretory products
into
vesicles in cells
