| Question | Answer |
|---|---|
| Three Na⁺ move inside a carrier protein (before a PO ₄³⁻ bind) to shapeshift the protein—this "pumps" Na⁺ outside the cell to sustain membrane potential. Name & total next ions pumped in, lateral to PO ₄³⁻'s release, & name this process. | Two potassium (K⁺) ions pump inside the cell. This process is called the "sodium-potassium pump" |
| What skin layer that’s also known as an “extra layer” for protection and mainly found to the palms & soles of the feet (additionally with digits)? | stratum lucidum |
| What skin layer releases “lamellar bodies” that ultimately gives impermeability lipid aspects to the top skin layer? | strata granulosum |
| What term is it called when a cell decreases it’s size? This term can be attached to a body feature such as muscles or organs to indicate properties being degenerative, or undertaking mass loss. | atrophy |
| Name the four nucleotides, or bases, in DNA and how they pair. | adenine (A) to thymine (T). and guanine (G) to cytosine (C) |
| Adenosine triphosphate (ATP) is an iconic piece for pumping ions out of a cell and cell’s membrane by channeling through a transport protein. What term best indicates this type of cellular energy mechanism? | Active transport |
| What major body system is least important for maintaining homeostasis | reproductive system |
| what is it called when any identical small molecules make up any large molecule | Polymer |
| Tissue hormones that are made of lipids are also called | prostaglandins |
| What protein was thought to be the cause of mad cow disease? | Prion |
