•
Phosphofructokinase (PFK)
Pyruvate Kinase (PK)
39- maltose , lactose, Sucrose disacride in lipids *diet*

37Axon , axon terminal
38- acetylecholinestrase
40- 4 disadvantages of IV route catabolism of fatty acids glucose synthesized by (glycerol)
- anabolic in nature=
- electron transport chain help in= phosphorylation citric acid cycle direct source of = باوجلا ناك نكمم شيا طبضلاب ركذا ام سب لاؤس هيلع اج acetyle co a?
• Citric acid cycle (condenses with acetyl CoA): to yield energy ATP
• Acetyl CoA
Oxalacetate
- Glucose synthesis enzyme= (glucose 6-phosphatase)
- conversion of pyruvate into oxalectate =(in mitochondria)
- end product of anaerobic= (lactic acid)
Number of fat adipose tissue & skeletal muscles... transporter increase by
=(insulin)
- liver glycogen degraded to yield= glucose
Aerobic Glycolysis: end product is pyruvate
Pyruvate kinase
FINAL final--]
