Cells
The powerhouse of the cell
What is the mitochondria?
Cell membranes are made primarily of
What are phospholipids?
The capacity to do work
What is energy?
The process cells use to generate energy in the form of ATP from food molecules.
What is cellular respiration?
All living organisms are composed of this smallest unit of life.
What are cells?
Major membrane components that can act as enzymes, transporters, or structural attachments for the cytoskeleton.
What are proteins?
The energy of motion
What is kinetic energy?
Where aerobic respiration takes place in eukaryotic cells.
What is the mitochondria?
This is where photosynthesis takes place.
What is the chloroplast?
These cellular structures are responsible for protein synthesis
What are ribosomes?
A passive transport process where substances move from areas of high to low concentration.
What is diffusion?
In these exergonic reactions, large molecules are broken down into smaller molecules.
What are catabolic reactions?
In this cytoplasmic process, glucose is split in 2, yielding 2 ATP.
What is glycolysis?
Molecules that absorb specific wavelengths of light.
What are pigments?
A group of membranes and organelles in eukaryotic cells that work to modify, package, and transport lipids and proteins.
What is the endomembrane system?
Water movement from areas of low solute concentration to areas of higher solute concentration.
What is osmosis?
Molecules which lower the activation energy of chemical reactions.
What are enzymes?
In this cycle, oxaloacetate is regenerated for each "turn" of the cycle".
Citric Acid Cycle
A collection of pigments surrounding a reaction center located in the thylakoid membrane.
What is a photosystem?
These structures inside chloroplasts and mitochondria support the idea that they originated as free-living bacteria.
What are DNA and ribosomes?
This transport process requires proteins and ATP to transport molecules against their concentration gradient.
The use of a reaction product to regulate its own production.
What is feedback inhibition?
This group of proteins in the mitochondria is responsible for ferrying electrons from high energy levels to lower energy levels.
What is the electron transport chain?
This process utilizes carbon dioxide to build sugars in plants and algae.
What is the Calvin Cycle?
