  • Objective: We will learn how hydrolysis and dehydration equations are written, that enzymes affect activation energy, and the difference between secretion and excretion.
  • Language Objective: I will explain dehydration, hydrolysis, activation energy, and the difference between excretion and secretion.
  • Homework: Draw a Venn diagram to compare and contrast Prokaryotic and Eukaryotic Cells

Warm-Up
  • 1. How do amoebas move? False feet (psuedopods)
  • 2. What is the function of cilia? To aid in movement/locomotion
  • 3. What is the function of flagella? To aid in movement/locomotion
  • 4. Cells use passive and active transport to move materials across the cell membrane to maintain _____________________.
  • a. Diffusionb. evolution c. homeostasis d. respiration
  • 5. What type of solution was the egg on left placed in?
  • a. Hypertonic
  • b. Hypotonic
  • c. Isotonic

Hydrolysis/Dehydration
  • Hydrolysis – adding water to a reaction
  • Dehydration – removing water from a reaction

Benedict’s Solution
  • The most common use for Benedict Solution is the detection of glucose in urine for the diagnosis of diabetes.

Excretion/Absorption/Secretion
  • Diabetics excrete glucose into their urine because they are unable to properly absorb it into their cells. After a positive diagnosis, additional tests are needed to quantify the amount of glucose excreted.
  • Excrete – it exits your body
  • Secretion – released within an organism (hormones)
  • Sugar = Glucose = Carbohydrate
