Document Summary

Cellular respiration: pathway of production of atp using glucose, glucose enters most cells by facilitated diffusion, may be increased in some cells by insulin. In body: glycogen -> glucose->atp, proteins, some aa converted to pyruvic acid or can enter krebs cycle directly, depending on body need ( and organ) may form new glucose ( liver, kidney) or atp ( most cells) Fats: primary storage form of e in the body ( triglycerides, broken down to form acetylcoa -> atp. Functions: support, protection of vital organs, attaches muscles and allows movement, red marrow produces rbc and wbc, stores ca2++ Bone ossification fig 6. 9,6. 11,6. 12, 6. 15: before week 8, the skeleton embryo constructed of fibrous membranes and hyaline cartilage, bone formation begins at approx. Intramembranous ossification: flat bones, cranial bones, clavicle, etc, develop from fibrous ct membrane, periosteum forms and osteoblasts under it lay down compact bone, fontanelles, unossified membranes in the skulls that remain at birth, ant.
