Two individuals (one elite endurance runner, one sedentary adult) begin jogging at the exact same moderate speed. The elite runner produces significantly less blood lactate in the first 3 minutes.  How their oxygen deficit compares at the onset of exercise. The physiological/cellular adaptation that causes this difference.

A soccer player transitions instantly from a light jog to an all-out 10-second sprint.  The primary bioenergetic pathway activated for the sprint. The specific intracellular trigger (modulator) that signals this pathway to accelerate ATP production.

Consider the Lewis structure shown below. Calculate the formal charge on the carbon atom. Use the equation: Formal Charge = Valence Electrons − Lone-Pair Electrons − (Bonding Electrons ÷ 2) Show all of your work on your scratch paper. Your work should include the setup and all calculations used to arrive at your final answer. Your scratch paper must be uploaded after completing the quiz according to the course instructions. Enter your answer as a whole number. Include the positive or negative sign if needed. Do not include units.

A molecule has four electron groups around the central atom and one lone pair. What is the molecular geometry?

What is the electron geometry around the oxygen atom?

Approximately what is the H-P-H bond angle in chlorophospine?

Amino acids are naturally occurring compounds that are the building blocks for many important biological molecules. One of the main amino acids is cysteine. Examine the Lewis structure of cysteine shown below. Click on every atom that has a tetrahedral electron geometry. Select all correct atoms. Remember that electron geometry is determined by the total number of electron groups (bonding pairs and lone pairs) surrounding an atom.

 Combine each pair of sentences into one compound sentence using a comma and and an appropriete coordinating conjunction. Be sure to keep the meaning the same and use correct capitalization and punctuation. The dog was scared. It protected its owner.

We didn’t see the sign. We didn’t hear the announcement.
