BIO: Exam 4
Unit 3 Jeopardy Questions
| Question | Answer |
|---|---|
| How can our bodies increase or decrease hormone responses? | 1. Change the amount of hormone transporters present 2. Change the number of receptors 3. Block or promote hormone receptor binding 4. Produce counteracting/amplifying hormones |
| How do our bodies maintain homeostasis with hormones? | We can alter hormone functions in different ways to adjust our internal environment changes based on external conditions. |
| Name the 3 types of hormones | 1. Amine 2. Protein/Peptide 3. Steroid/Lipid |
| What kind of hormone is inulin? | Insulin is a Protein/Peptide hormone |
| What are the 2 main types of receptors? (broadly) | 1. Extracellular - Outside cell membrane (transmembrane receptors) 2. Intracellular - Inside cell in cytosol or nucleus |
| What type of receptor is used by insulin? And what happens when it binds? | Extracellular; phosphorylation of the intracellular portion of receptor occurs in the process |
| Only what types of molecules can diffuse through the semi-permeable phospholipid bilayer? | Non-polar, neutral molecules (or water) |
| Why are fatty acids allowed to pass through the intestinal cell membrane? | Fatty acids are largely nonpolar (hydrophobic), allowing them to pass while other molecules like amino acids are too polar and cannot |
| What type of molecule will dissolve in a hydrophobic solution? | A hydrophobic/nonpolar molecule |
| Considering diffusion, active transport, and passive transport, which require ATP and how do their concentrations move? | Active transport bc it goes against the concentration gradient Diffusion – no ATP, high --> low Passive Transport – no ATP, high --> low Active Transport – requires ATP, moves against concentration gradient |
| Do polar molecules need carrier proteins to move through the blood or the phospholipid bilayer? | Polar molecules can move through polar, water-based blood without a carrier protein but polar molecules need a carrier protein move through the hydrophobic lipid bilayer |
| What represents the receptors, effectors, and control center of the negative feedback in glucoregulation? What is the role of the liver in both hyperglycemia and hypoglycemia? | Control Center: Pancreas Effector: Liver Receptor: Hypothalamus Hypoglycemia: liver breaks down glycogen into glucose Hyperglycemia: liver creates glycogen from glucose, but doesn’t release it |
| What are 3 ways the glucoregulatory system could be altered that would decrease blood glucose levels? | Overproduction of insulin, inhibition of GLUT4 translocation, etc. (check slides?) |
| Does insulin bind to intracellular or extracellular receptors? | Extracellular receptors because the binding passes on a signal that triggers other cellular events |
| Differentiate between glucose, glycogen, glucagon, and GLUT4 | Glucagon – hormone that increases blood glucose Glycogen – storage for glucose; polysaccharide GLUT 4 - glucose transporter Glucose – monosaccharide |
| Are carbon and oxygen being oxidized or reduced in the process of cellular respiration? | Carbon is oxidized Oxygen is reduced |
| In general, where does cellular respiration occur? | Mitochondria of the cell |
| What are the reactants and products of the cellular respiration process? | Reactants: Glucose + O2 Products: ATP + CO2 + H2O |
| Where does glycolysis occur and what is created in the process? | Glycolysis occurs in the cytoplasm. 1 glucose is converted into 2 molecules of pyruvate (3C), 2 net ATP produced from ADP, NAD+ converted to 2 NADH |
| Is NAD+ being oxidized or reduced during glycolysis? | NAD+ accepts an electron and is reduced |
| What is the difference between type 1 and type 2 diabetes? | Type 1 diabetes --> the body is not producing enough insulin Type 2 diabetes --> the body is not responding to insulin after being overly exposed |
| How is diabetes diagnosed? | Blood tests to see if there are elevated levels of blood glucose |
| What is the function of digestive enzymes? | Break down large polymers to monomers for further digestion (our body can only absorb monomers) |
| What enzyme is responsible for breaking down carbohydrates? | Amylase |
| What is the difference between saturated and unsaturated fats? | Unsaturated fats contain one or more double bonds Saturated fats only contain single bonds |
