The Cell
This organelle, often referred to as the "powerhouse" of the cell, is responsible for generating energy in the form of ATP.
What is Mitochondria?
This type of lipid consists of a glycerol molecule bonded to three fatty acids and is a major component of fats and oils.
What are Triglycerides?
This polysaccharide forms Alpha 1-4 linkages, found only in Animals and is the primary source of energy for cellular activities.
What is Glycogen? (Glucose)
This type of transport protein facilitates the movement of specific ions across the cell membrane, often against their concentration gradient.
What are Carrier Proteins?
These two processes involve the movement of materials across the cell membrane via vesicles.
What is endocytosis and exocytosis? Bulk Transport
This organelle receives, modifies, and packages proteins and lipids from the endoplasmic reticulum for transport to other parts of the cell or for secretion.
What is Golgi Apparatus?
These organic molecules serve as the main structural components of cells and tissues, and they also function as enzymes, antibodies, and transport molecules.
What are Proteins?
This type of fat has no double bonds between carbon atoms in its fatty acid chains and is typically solid at room temperature.
What are Saturated Fats?
These transport proteins use ATP energy to move molecules across the cell membrane, often against their concentration gradient.
What are Integral Proteins?
This term refers to the disruption of a protein's native structure, resulting in loss of its function, caused by factors such as high temperature or extreme pH.
What is Denature?
Composed of microtubules, microfilaments, and intermediate filaments, this cellular structure provides shape, support, and facilitates intracellular transport.
What is Cytoskeleton?
This complex carbohydrate, found in plant cell walls, is composed of long chains of glucose molecules bonded together.
What is Cellulose?
These fats contain one or more double bonds between carbon atoms in their fatty acid chains and are typically liquid at room temperature.
What are Unsaturated Fats?
This type of transport protein facilitates the movement of water molecules across the cell membrane, allowing for osmosis.
What are Aquaporins?
This type of endoplasmic reticulum lacks ribosomes on its surface and is involved in lipid synthesis and detoxification within the cell.
These membrane-bound organelles contain enzymes that break down cellular waste and debris in animal cells.
What are Vesicles & Vacuoles?
This type of lipid consists of a phosphate group, glycerol, and two fatty acid chains, and it is a major component of cell membranes.
What are Phospholipids?
These structures, such as alpha helices and beta sheets, are common motifs found in the secondary structure of proteins.
What is Protein Secondary Structure?
This term refers to the movement of molecules from an area of higher concentration to an area of lower concentration across the cell membrane.
What is Diffusion?
This level of protein structure refers to the overall three-dimensional arrangement of multiple polypeptide chains in a protein complex.
What is Protein Quaternary Structure?
This double-membraned organelle contains its own DNA and is thought to have originated from endosymbiosis with ancient prokaryotic cells.
What is Mitochondria? Note: Endosymbiotic Theory
This polysaccharide, found in the exoskeletons of arthropods and the cell walls of fungi, is composed of Beta 1-4 linkages.
What is Chitin?
This level of protein structure refers to the sequence of amino acids in a polypeptide chain.
What is Protein Primary Structure?
This integral membrane protein actively transports three sodium ions out of the cell and two potassium ions into the cell against their respective concentration gradients, using ATP as an energy source.
What is Sodium Potassium Pump?
These two types of unsaturated fats differ in their molecular arrangement around a double bond, with one having hydrogen atoms on the same side of the carbon chain, and the other having hydrogen atoms on opposite sides.
What are Cis & Trans Fats?
