Theory
This theory proposes that mitochondria and chloroplasts originated from once free-living organisms
What is the endosymbiotic theory?
These are the two factors that can denature an enzyme and stop it from functioning properly.
What are temperature and pH
This is the distinguishing feature of eukaryotic cells compared to prokaryotic cells.
What are membrane-bound organelles (or nucleus)?
This structure within plant cells converts solar energy into chemical energy
What is the chloroplast?
"This structure found in eukaryotic cells but absent in prokaryotic cells stores genetic information."
What is the nucleus?
This is the number of principles within the Cell Theory
What are 3
Enzymes lower this aspect of a chemical reaction to speed up the process.
What is activation energy?
This scientist proposed that all living organisms are composed of cells
Who is Theodor Schwann or Matthias Schleiden?
This organelle is responsible for the synthesis of lipids, including phospholipids
What is the smooth ER
This is the term used to describe the level at which enzymes are no longer effective due to all substrates being used."
What is substrate saturation?
The presence of this within mitochondria is one of the main arguments supporting the endosymbiotic theory
What is mitochondrial DNA?
This part of an enzyme is where the substrate binds.
What is the active site?
Root word "Cyto" means
What is a cell?
This part of the cell modifies, packages, and transports proteins."
What is the Golgi apparatus?
This organelle contains digestive enzymes that break down waste materials in the cell."
What are lysosomes?
These are the 3 principles of Cell Theory.
All living organisms are composed of one or more cells.
The cell is the basic unit of structure and function in living organisms.
All cells arise from pre-existing cells.
(Daily Double):
This process refers to the destruction of an enzyme's structure due to high temperatures or extreme pH, making it non-functional.
What is denaturation?
What does D C C R stand for?
DNA Dogs
Cytoplasm Can't
Cell Membrane Cook
Ribosomes Ribs
This large structure in plant cells stores water, nutrients, and waste, helping to maintain turgor pressure.
What is the central vacuole?
This is another name for the cell membrane (synonym)
What is the plasma membrane?
Daily Double
Chloroplasts are believed to have evolved from this group of bacteria
What are cyanobacteria?
This enzyme speeds up the breakdown of hydrogen peroxide and is found in peroxisomes.
What is catalase?
This scientist's observation of cork led to the discovery of cells
Robert Hooke?
These molecules are the primary components of the cell membrane, allowing for its semi-permeability."
What are phospholipids?
This term refers to molecules that bind to an enzyme and inhibit its activity by changing the shape of the enzyme’s active site
What are non-competitive inhibitors?
