10-24-2012

  • 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. evolutionc. homeostasisd. respiration

  • 5. What type of solution was the egg on left placed in?

  • a. Hypertonic

  • b. Hypotonic

  • c. Isotonic


Hydrolysis/Dehydration

Hydrolysis or Dehydration?


Hydrolysis/Dehydration

Hydrolysis or Dehydration?


Hydrolysis/Dehydration

  • Hydrolysis – adding water to a reaction

  • Dehydration – removing water from a reaction


Enzymes – lower activation energy(SPEED UP A CHEMICAL 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


Excretion/Absorption/Secretion

  • Osmosis

  • Diffusion

  • Dehydration

  • Hydrolysis

  • Homeostasis

  • Enzymes

  • Hypotonic

  • Hypertonic
