Terms in this set (35)
Add the number of protons and neutrons.
How many protons are in the nucleus.
Subtract the atomic number from the mass number.
Subtract the number of neutrons from the mass number.
Will equal the number of protons.
Has monomers that are called nucleotides. Has two types, DNA and RNA.
Involved in nearly every dynamic function in your body and are very diverse, each with a specific structure and function in the body. Amino Acids are the monomers for this organic molecule.
Range from small sugar molecules (monomers) to large polysaccarides. Starch is a monomer for this organic molecule. Monosaccarides are the simplest form of these.
Insoluble (hydrophobic,or water fearing) compounds. They are important in long-term energy storage and contain twice as much energy as a polysaccharide. they consist mainly of carbon and hydrogen atoms linked by nonpolar colvalent bonds. Fatty Acids are teh main monomer for this organic molecule.
A type of nucleic acid. It is inherited from an organism's parents, it provides directions for its own replication, programs a cell's activities by directing the synthesis of proteins, and does not build proteins directly. This works through an intermediary, RNA. Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
DNA is transcribed into this inside of the nucleus. this is translated into proteins in the cytoplasm. Instead of thymine (T), it has uracil (U).
Converts the chemical energy in foods to chemical energy in ATP. Sugar is broken down to carbon dioxide and water and the cell captures some of the released energy to make ATP. This takes place in the mitochandria in eukaryotic cells.
Cellular Respiration Formula
C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP + Heat
A substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. These help speed up chemical reactions.
An enzyme that catalyzes the reduction of hydrogen peroxide.
A mechanism that prevents fertilization from occurring.
A mechanism that reduces the viability or reproductive capacity of hybrid offspring.
Contains most of the cell's DNA and controls the cell's activities by directing protein synthesis by making messenger RNA.
A prominent structure in the nucleus and a site of ribosomal RNA synthesis.
Are organelles that carry out cellular respiration in nearly all eukaryotic cells.
Make proteins for the cell.
Photosynthesizing orgenelles of plants and algae. They are partitioned into compartments.
Serves as a molecular warehouse and processing station for products manufactured by the ER.
Has bound ribosomes that stud the outer surface of the membrane. Makes additional membrane for itself and secretoryproteins.
Lacks attached ribosomes. Involved in a variety of metabolic processes including production of enzymes and storage of calcium ions.
A compartment that stores water and a variety of chemicals. Has a variety of functions... digestive, contains pigments, and can contain poisons that protect plants.
A double membrane that has pores that regulate entry and exit of large molecules.
Forms a flexible boundary between the living cell and its surroundings.
Metabolic compartments that do not originate from the endomembrane system.
A membrane enclosed sac of digestive enzymes. Made by the rough ER and processed in the golgi apparatus.
A complex of proteins and DNA that appears as a diffuse mass within the nucleus.
Carry the genes made of DNA.
The jelly like fluid inside of the cell.
The region where the DNA is coiled. Found in prokaryotic cells.
Long hair like structures that help the cell move.
