THESE two structures are common to both prokaryotic and eukaryotic cells.
What are PLASMA MEMBRANE and CYTOPLASM?
An organic molecule contains this element.
What is CARBON?
Through its gills, a fish exchanges gases to regulate oxygen levels in order to maintain THIS balance?
What is HOMEOSTASIS?
Proteins do most of the work in cells and are required for the structure, function, and regulation of all the body's THESE.
What are TISSUES and ORGANS?
This word, from the Greek for "self feeder," describes an organism that can produce its own food.
What is AUTOTROPH?
The Golgi apparatus is a one of THESE, a subunit within a cell that has a specialized function.
What is an ORGANELLE?
What are MACROMOLECULES?
The pH level is a measure of acidity or THIS of an aqueous solution scaling from 1-14.
What is ALKALINITY (or basicity)?
The first step of protein synthesis, that is making a protein from a cell's genetic code, is THIS, which literally means "written across."
What is TRANSCRIPTION?
Photosynthesis occurs in the chloroplast. Oxygen is an output, and THIS chemical compound is an input.
What is CARBON DIOXIDE?
Commonly known as the "powerhouse of the cell," THIS is the site of cellular respiration.
What is the MITOCHONDRIA?
In a metabolic reaction, THIS speeds up the reaction without being consumed.
What is an ENZYME?
In a process called diffusion, particles move from THIS to THIS concentration area.
What is HIGH TO LOW?
Protein assembly continues until the ribosome encounters THIS sequence of three nucleotides that does not code for an amino acid.
What is a STOP CODON?
In order to regulate the amount of water that it releases, a plant has THESE on its leaves that open and close.
What are STOMATA?
THIS structure, abbreviated ER, can be rough or smooth, depending on the presences of surface ribosomes.
What is ENDOPLASMIC RETICULUM?
This type of reaction forms a polymer from two monomers.
What is DEHYDRATION SYNTHESIS?
Active transport, moving molecules or ions across a cell membrane from a lower to higher concentration, requires THIS.
What is ATP? (or energy)
During translation, mRNA carries information from DNA to a ribosome, and then THIS carries amino acids to the ribosome to build the amino acid sequence that forms a protein.
What is tRNA? (or transfer RNA)
During photosynthesis, THESE molecules capture solar radiation so it can converted in the bonds of carbohydrate molecules.
What is CHLOROPHYLL?
THIS theory proposes that early eukaryotic cells were formed from simpler prokaryotes.
What is ENDOSYMBIOSIS?
More energy is released than used to form new bonds in THIS type of reaction.
What is EXOTHERMIC?
In order to maintain homeostasis, THESE loops act to oppose a stimulus like too high body temperature or low blood sugar.
What are NEGATIVE FEEDBACK LOOPS?
Snake venom is a mixture of various proteins, peptides, and nucleotides that break down muscle tissue in prey. In Pennsylvania, the Eastern copperhead snake forms its venom by breaking down and synthesizing WHAT molecules from prey?
What are SUGAR MOLECULES?
The carbohydrate molecule produced by photosynthesis has THIS chemical formula.
What is C6H12O6?
