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
Absorption of Nutrients (pg 12)
• Passive Transport: Does not require energy. Substances move from high concentration to low concentration– Diffusion: Move through cell membrane– Facilitated diffusion: Move through a channel
protein in the cell membrane

proteins to move substances from low concentration to high concentration
