This is an example of a simple carbohydrate.
What is glucose? (or fructose, or galactose)
These are the three steps in the flow of genetic information: _____ to _____ to _____.
What is DNA to mRNA to protein?
Transport across a membrane that requires energy.
What is active transport?
What is a chemical bond?
This is the final electron acceptor in the electron transport chain.
What is oxygen?
These are areas around the nucleus of an atom, each with a different energy, that contain orbitals that may be filled with electrons.
What are shells?
The part of the enzyme where the substrate binds.
What is the active site?
Diffusion of water across a membrane.
What is osmosis?
The kind of energy an object has due to its location or structure.
What is potential energy?
The process of harvesting energy from food when oxygen is not available.
What is fermentation?
The process by which all living organisms maintain stable internal environments.
What is homeostasis?
This is the kind of RNA that carries amino acids to the ribosome.
What is tRNA?
A solution with a low solute concentration relative to another solvent.
What is a hypotonic solution?
Number of phosphate groups that ATP has.
What is 3?
The three steps of cellular respiration.
What are glycolysis, the Krebs cycle (or citric acid cycle), and electron transport chain?
The number of amino acids that exist.
What is 20?
This is how enzymes speed up chemical reactions (in terms of energy.)
What is they lower activation energy?
What is facilitated diffusion?
The 2 stages of photosynthesis.
What are the light reactions and the Calvin Cycle?
This is the other electron carrier that is produced during glycolysis and the Krebs cycle, in addition to NADH.
What is FADH2?
The first three stages of the scientific method.
What are observation, question, and hypothesis? (The last three stages are predictions, testing, and conclusion.)
This is one type of cell junction.
What is tight junction? (or adhering junction, or gap junction)
The name for vesicular transport into a cell.
What is endocytosis?
Produces in the light reactions of photosynthesis, this molecule is an electron carrier.
What is NADPH?
This is the product of glycolysis (in addition to NADH and ATP, this is what is produced.)
What is pyruvic acid? (2 molecules of it)
