2. 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

3. Hydrolysis/Dehydration Hydrolysis or Dehydration?

4. Hydrolysis/Dehydration

5. Hydrolysis/Dehydration Hydrolysis – adding water to a reaction Hydrolysis – adding water to a reaction Dehydration – removing water from a reaction Dehydration – removing water from a reaction

6. Enzymes – lower activation energy (SPEED UP A CHEMICAL REACTION)

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

8. 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. 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 Excrete – it exits your body Secretion – released within an organism (hormones) Secretion – released within an organism (hormones) Sugar = Glucose = Carbohydrate Sugar = Glucose = Carbohydrate

9. Excretion/Absorption/Secretion Osmosis Osmosis Diffusion Diffusion Dehydration Dehydration Hydrolysis Hydrolysis Homeostasis Homeostasis Enzymes Enzymes Hypotonic Hypotonic Hypertonic Hypertonic DNA RNA Nucleotide (3 parts) Carbohydrates Centromere Centrioles Mitosis S Phase –Synthesis of DNA Cell Cycle Lytic Cycle (viruses) Bacteria Living organisms Cell membrane Prokaryote Eukaryote
