Basic Chemistry
Subatomic particle that contributes to the atomic mass, but lacks a charge.
What is a neutron
Organic compounds always contain this.
What is carbon
I am a cell boundary that acts as a selective barrier and am composed primarily of phospholipids and proteins
What is the plasma membrane
I am a type of reaction that releases energy. I am spontaneous.
What is exergonic?
This cell structure connects to the kinetecore (attached at the centromere of the chromosomes) and is used to pull the chromosomes apart during anaphase of both cycles.
What is microtubules (miotic spindle fibers).
The property of water that accounts for its tendency to form hydrogen bonds with other water molecules.
What is polarity.
I am a dimer. I am made of glucose and galactose. I cause upset stomach in some individuals
What is lactose.
I am a section of membrane found in eukaryotic cells. I am connected to the nuclear envelope and have two distinct sections, one with ribosomes and one without ribosomes. One section is vital for protein synthesis (especially for excreated proteins) and one works with in lipid synthesis, carbohydrate metabolism and detoxification.
What is the endoplasmic reticulum?
I shut down enzymes by binding to an enzyme at a site that isn't its active site, causing it to change shape and preventing the reaction from moving forward. I bind equally well to the enzyme whether it has a substrate bound or not.
This is the section of the cell cycle where the cell separates into daughter cells.
What is cytokinesis
The weak chemical interactions between molecules that are near each other. They can add up to be significant and play a role in protein folding
What are van der Waals interactions
This is a type of organic compound with a 1:2:1 of C:H:O. It is a polymer. It is an energy storage molecule in animals.
What is glycogen
I am a type of connection formed between plant cells. the membranes of the cells connect here in narrow openings in the cell wall. These allow for free movement of cytoplasm between plant cells.
What are plasmadesmata?
I am a class of molecules used for long distance signalling in plants and animals. I am released in to the circulatory system.
What are hormones?
This is a term that describes programmed cell death that is a normal part of embryonic development. It is severely hindered or entirely non functional in cancerous cells.
What is apoptosis?
Water has a relatively high value for this property when compared with other substances with similar atomic masses. It is this high value that allows for evaporative cooling to effectively cool biological systems.
What is heat of vaporization
This experiment is 1953
What is the Miller-Urey experiment
This describes a solution that has more solutes in it that does a cell that comes in contact with it. Cells placed in this type of solution will either shrivel or plasmolyse depending on cell type.
What is hypertonic?
I am a class of membrane receptor proteins. A key step in my pathway is dimerization, phosphorylation of tyrosines, and secondary relay proteins.
What are Receptor tyrosine Kinases
In this phase, homolougous chromosomes are aligned randomly at the metaphase plate.
What is prophase I?
An increase in this in the atmosphere is leading to ocean acidification. This acidification has been blamed for diminishing fisheries as well as the deaths of coral reefs around the world.
What is CO2
I am a type of organic compound that contains N, C, H, and O. My structure is a five-membered ring, combined with a six-membered ring. I combine with a sugar and phosphate to make a 2 of the 5 monomers on nucleic acids.
I am the purines (Adenine and Guanine).
I am a hydrocarbon ringed molecule with a hydroxyl group. I reduce membrane fluidity at moderate temperatures and increase it at low temperatures. I am found only in the cell membranes of animal cells.
What is cholesterol.
I am a secondary signaling molecule activated by adenylyl cyclase and deactivated by a phosphosiesterase. I am related in structure to the monomers of DNA and RNA
What is cyclic AMP
In these TWO phases sister chromtids seperate.
What are Anaphase of mitosis and anaphase II of Meiosis
