Complete question:
Imagine a newly discovered biological molecule that is mostly hydrophobic in its structure. This new molecule will most likely be classified as a___________.
a. Proteins
b. Lipids
c. Nucleic acids
d. Carbohydrates
Answer:
b. Lipids
Explanation:
Lipids are the biomolecules that are mostly nonpolar in nature. Storage lipids such as fatty acids and oils have small or long chains of hydrocarbons. This makes them largely hydrophobic. Similarly, phospholipids have fatty acid chains that make their hydrophobic component. Steroids are also the lipids that have a distinct sterol nucleus in their structure. This makes then hydrophobic. Therefore, most of the lipids have structural components that make them largely hydrophobic molecules. So, the newly discovered molecule is most likely a lipid.

Explanation:
The white board displays helpful info with regards to a QR scanner associated with the day's lesson plan. The shelves on the far end of the classroom holds up relevant books and other objects that will prove educational for the students. Some schedules have been put up too for the ease of the students.
Answer: Amino acids are absorbed via a Sodium cotransporter, in a similar mechanism to the monosaccharides.
Explanation: Amino acids are absorbed via a Sodium cotransporter, in a similar mechanism to the monosaccharides. They are then transported across the alabaster membrane via facilitated diffusion. Di and tripeptides are absorbed via separate H+ dependent cotransporters and once inside the cell are hydrolyzed to amino acids.

1. Action potential reaches the axon terminal and depolarizes it.
2. Depolarization opens voltage-gated calcium channels, enabling influx of Ca into the neuron.
3. Calcium binds to specialized proteins on vesicles (containing pre-made acetylcholine) and triggers them to fuse with the neuron membrane at the synapse.
4. Exocytosis of acetylcholine into the synaptic cleft occurs.
5. Acetylcholine diffuses across the synapse and binds to nicotinic receptors on the end plate of the myocyte.
6. Activated nicotinic receptors, themselves ion channels, cause cation influx into the myocyte and generate an end plate potential. This eventually gives rise to the full depolarization within the myocyte that enables contraction.
