Brrrr... shivers point to this type of feedback in the human body.
What is negative feedback?
Wasn't this a song in The Lion King? Water functions as the solvent of ____.
What is life?
A house divided... If a strand of DNA came apart down the center, this type of bond would be compromised.
What are hydrogen bonds?
This chemical characteristic allows the cell membrane to be selectively permeable.
What is its amphipathic characteristic?
Just a tune-up... The Golgi apparatus modifies proteins after they arrive from this organelle.
What is the rough endoplasmic reticulum?
Anatomical criticism? These are the two types of feedback systems in the human body.
What are negative and positive feedback?
If blood glucose rises after a meal, the pancreas detecting that increase represents this homeostatic component.
What is the receptor? (detecting a deviation from the set point)
It's my turn to use the iPad! This type of covalent bond involves unequal sharing of electrons between atoms.
What is a polar covalent bond?
Two faced... In a phospholipid bilayer, this explains why heads face out and tails stay in.
What is amphipathic structure with hydrophilic heads and hydrophobic tails?
These are the main functions of the smooth endoplasmic reticulum.
What are

- carbohydrate metabolism
- drug and alcohol detoxification
- storage of ions
High Voltage! A cell with high ATP demand would have a large lot of these organelles.
What are mitochondria?
Good things come in threes, and these are the three parts of a homeostatic system.
What are the receptor(s), control center, and effector(s)?
If you lose nutrients after sweating, the structure releasing hormones to minimize loss would be this part of a homeostatic control system.
What is an effector (restoring levels to the set point)?
When a sucrose is split into glucose and fructose this reaction occurs and it uses this "solvent". (two answers)
What is hydrolysis (using water)?
If blood pH drops below normal, this ion's concentration (level) is likely to have increased.
What is hydrogen ion (H⁺) concentration?
If a molecule cannot pass through a lipid bilayer, it likely has this chemical property.
What is being polar/hydrophilic?
New phone who this? If membrane glycoproteins are absent, cells would have difficulty performing this function.
What is cell recognition and adhesion?
A tennis players chance to take it all... or the referenced value in a negative feedback system.
What is the set point?
This level of organization in the human body is what maintains homeostatic levels.
What are organ systems?
When amino acids join to form a peptide bond, this type of reaction takes place.
What is a condensation (dehydration) reaction?
All tangled up! The (molecular) structural feature that makes unsaturated fats more fluid than saturated fats is this.
What is are carbon–carbon double bonds?
1+1. The structure formed by the merging of a primary lysosome and a phagosome.
What is a secondary lysosome?
Chapter 1! If the plasma membrane loses selective permeability, the cell would lose its ability to maintain this bodily process.
