Homeostasis
Homeostasis is the maintenance of a ____ ____ environment.
What is "constant internal?"
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?
Eureka! The principal fuel molecule used by cells in the human body.
What is ATP
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 the increase represents this homeostatic component.
What is the receptor? (detecting a deviation from the set point)
When a sucrose is split into glucose and fructose this reaction is occurring with this "solvent".
What is hydrolysis (using water)?
Two faced... In a phospholipid bilayer, this explains why heads face water and tails hide inward.
What is amphipathic structure with hydrophilic heads and hydrophobic tails?
Energymaxxing! 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 working to restore nutrient levels to 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?
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?
Just a tune-up... The Golgi apparatus modifies proteins after they arrive from this organelle.
What is the rough endoplasmic reticulum?
A tennis players chance to take it all... or the decided value in a negative feedback system.
What is the set point?
You design a system of hormonal regulation with these three vital components.
What are receptors, a control center (integrator), and effectors?
I need a sip... 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 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 most immediately lose this ability.
What is maintaining homeostasis?
Just following orders! The two bodily systems direct the processes that maintain homeostasis.
What are the nervous and endocrine systems?
Insulin is released into the blood by the pancreas after recognizing elevated glucose levels. These feedback systems and bodily systems were used in that process.
What are the nervous and endocrine systems?
And
What is a negative feedback system?
Some assembly required. When glycerol combines with three fatty acids the resulting molecule is this.
What is a triglyceride?
Some wiggle room! If you wanted a membrane that is more fluid at low temperatures, you would increase this type of fatty acid.
What are unsaturated fatty acids?
The long walk... A cell specialized for movement would emphasize this cytoskeletal structure (bonus answer: for the associated protein interaction.)
What are microtubules interacting with motor proteins?
