What are the monomers of lactose?
Glucouse and Galactose.
What is Endocytosis?
When cells take large molecules in vesicles that bud inward.
What happens when lysosomes burst in the cell?
When it bursts, lysosome will digest cellular substances.
What is active transport?
The movement of molecules across a membrane that requires energy.
Compare between saturated fats and unsaturated fats.
*Saturated fats: Has the maximum number of hydrogens. Solid at room temprature.
*Unsaturated fats: Has fewer than the maximum number of hydrogens at the double bond.
Liquid at room temprature.
What is the function of golgi apparatus?
Receives products form the ER through transport vesicles, refines it, stores and then distribute it to the other organelles or the plasma membrane.
What is the difference between DNA and RNA?
DNA sugar is deoxyribose. RNA sugar is ribose.
DNA has the base thymine(T). RNA has the base uracil(U).
DNA exists as double helix. RNA is single-stranded.
What is common between prokaryotic cell and eukaryotic cell?
They both have:
*Cytosol
*Plasma membrane
*Chromosomes
*Ribosomes
What is the function of ribosomes?
Responsible for protein synthesis.
What is the function of nucleus?
Control center of the cell and contains the DNA that stores information and produce protein.
What is the cell theory?
All living things are composed of cells and that all cells come from earlier cells.
What is hydrolysis?
Breaks bonds between monomers and adds a molecule of water.
What is the complimentary strand of DNA that has AGTCCGC?
TCAGGCG.
List 2 differnces between eukaryotic cell and prokaryotic cell.
Eukaryotic cells have organelles.
Eukaryotes have nucleus that contain dna while prokaryotes have no nucleus and the dna is in a Nucleoid
What is exocytosis?
The movement of large molecules using vesicles out of the cytoplasm through plasma membrane.
What is passive transport?
The movement of a molecule across the membrane that doesn’t require energy.
What are 2 organelles that have their own DNA?
Mitochondrea and Chloroplast.
How do enzyme speed up a chemical reaction?
by reducing the amount of activation energy required to break the bonds of reactant molecules.
What is cytoplasm?
region between the nucleus and plasma membrane. It consists of cytosol+organelles.
Define lactose intolerance?
Inability to digest lactose.
Define isotonic solution?
solution that has an equal concentration of solute
What is the difference between cilia and flagella?
Flagella are longer and move in a whiplike motion. Cilia are shorter and more numerous.
Function of smooth endoplasmic reticulum?
Produce lipid with steroids and help detoxify drugs in liver cells.
Fat molecules are made of ?
Made of glycerol molecule with three fatty acid.
