The study of tissues
What is histology?
The ability to maintain stable internal conditions.
What is homeostasis?
Name two of the four major elements that make up 96% of the body.
What are carbon, hydrogen, oxygen, and nitrogen?
The building blocks of proteins.
What are amino acids?
Reaction type that builds larger molecules from smaller ones.
What is synthesis (anabolic)?
The smallest unit of life.
What is the cell?
The type of feedback that reverses a stimulus.
What is negative feedback?
A bond formed by transfer of electrons.
What is an ionic bond?
The sugar in DNA.
What is deoxyribose?
Reaction type that breaks larger molecules into smaller ones.
What is decomposition (catabolic)?
The plane that divides the body into right and left parts.
What is the sagittal plane?
This system removes waste products from the body.
What is the excretory (urinary) system?
The universal solvent in cells.
What is water?
The main component of cell membranes.
What is phospholipids?
The reaction C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O + ATP.
What is oxidation-reduction reaction?
Approach that studies one organ system at a time
What is systemic approach
Give an example of positive feedback.
What is labor contractions (or blood clotting)?
The energy stored in muscles while sitting still.
What is potential energy?
The structural difference between DNA and RNA.
What is DNA is double-stranded with thymine, RNA is single-stranded with uracil?
A catalyst that speeds up reactions without being consumed.
What is an enzyme?
Approach that studies all structures in one area
What is regional approach
Why is a body temperature of 105°F dangerous at the molecular level?
What is proteins and enzymes denature (now explain denature!!)
Why are hydrogen bonds important in biological systems?
What is they stabilize DNA, proteins, and water properties?
Compare fibrous and globular proteins and give an example of each.
What is fibrous = structural like collagen, globular = functional like hemoglobin?
Why is water’s high heat capacity important for the body?
What is it prevents rapid changes in body temperature, maintaining homeostasis?
