digestive types of transport

Metabolism (pg 12)

• Sugars: major fuel used for making ATP in cells. Excess is stored as glycogen or fat

Metabolism (pg 12)

• Sugars: major fuel used for making ATP in cells. Excess is stored as glycogen or fat

• Fats: used to make ATP, build myelin sheaths and cell membranes, insulate and cushion organs

Metabolism (pg 12)

• Sugars: major fuel used for making ATP in cells. Excess is stored as glycogen or fat

• Fats: used to make ATP, build myelin sheaths and cell membranes, insulate and cushion organs

• Proteins: rarely used to make ATP. Broken apart into amino acids which are reassembled into enzymes and structural proteins (muscle fibers, keratin, etc.)

Absorption of Nutrients (pg 12)

• Passive Transport: Does not require energy. Substances move from high concentration to low concentration

Absorption of Nutrients (pg 12)

• Passive Transport: Does not require energy. Substances move from high concentration to low concentration– Diffusion: Move through cell membrane
