Transcript

  • 1. Can you solve this puzzle?RULES:• You cannot turn the plastic bag inside out• You cannot dump the glucose molecules through the top of the plastic bag• You cannot cut holes in the bag• Glucose molecules must enter the cell through a solid part of the bag• Glucose must remain grouped together once it enters the cell• You are allowed to use your hands on the inside of the bag.• When your group feels like you have figured this challenge out, raise your hand so Ms. Bengston can check your solution!
  • 2. Active Transport•cell uses energy•actively moves molecules to where they are needed•Movement from an area of low concentration to anarea of high concentration•(Low  High)•Three Types:
  • 3. Sodium PotassiumTypes of Active Transport Pumps (Active Transport using proteins)1. Protein Pumps -transport proteins thatrequire energy to do work •Example: Sodium / Potassium Pumps are important in nerve responses. Protein changes shape to move molecules: this requires energy!
  • 4. Types of Active Transport• 2. Endocytosis: taking bulky material into a cell • Uses energy • Cell membrane in-folds around food particle • “cell eating” • forms food vacuole & digests food • This is how white blood cells eat bacteria!
  • 5. Types of Active Transport3. Exocytosis: Forces material Endocytosis & Exocytosis out of cell in bulk animations • membrane surrounding the material fuses with cell membrane • Cell changes shape – requires energy • EX: Hormones or wastes released from cell
