Following glycolysis and the citric acid cycle, but before the electron transport chain and oxidative phosphorylation, the carbon skeleton of glucose has been broken down to CO2 with some net gain of ATP. Most of the energy from the original glucose molecule at that point in the process, however, is stored in the form of which of the following molecules?

Cells that are infected, damaged, or have reached the end of their functional life span often undergo “programmed cell death.” This controlled cell suicide is called apoptosis. Select the appropriate description of this event on a cell’s life cycle.

Put the steps of the process of signal transduction in the order they occur. 1. A conformational change in the signal-receptor complex activates an enzyme. 2. Protein kinases are activated. 3. A signal molecule binds to a receptor. 4. Target proteins are phosphorylated. 5. Second messenger molecules are released.

In addition to activating or inhibiting enzymes through allosteric regulation, what other means does a cell use to control enzymatic activity?

POC: HROB Math Calculations The nurse is verifying a dose of Methotrexate as a second RN verifier for a client that has been diagnosed with an unruptured ectopic pregnancy.  The provider ordered the client to receive Methotrexate 30 mg IM one dose now.  The Methotrexate is available in a 150 mg / 1mL vial.  How many milliliters (mL) will be in the syringe to be administered?  Provide a numerical answer only.  Reminder: 1. Apply the rounding rules 2. Apply leading zeros 3. Do not use trailing zeros

TCH 1 – MATH Calculation (VAL) A newly licensed registered nurse has admitted a woman with preeclampsia with severe features to the Labor/Delivery Unit. The Healthcare Provider has ordered:   Magnesium Sulfate 6 Gram loading dose of to be infused over 30 minutes IV piggyback.    The Healthcare Provider has ordered:  Prepare Magnesium Sulfate 40 Grams in 1000 mL of LR.  The preceptor checks calculations and recognizes that the newly licensed registered nurse does not require further teaching when the IV pump is programmed to infuse the loading dose at the ______ milliliters per hour? Provide a numerical answer only.  Reminder: 1. Apply the rounding rules 2. Apply leading zeros 3. Do not use trailing zeros

Lactase is an enzyme that digest lactose.
