100
name the type of organic molecule that an enzyme is
What is protein?
100
name the energy molecule that helps to move ions against their concentration gradient
What is ATP?
100
water's ability to dissolve a solute gives water this property
What is a universal solvent?
100
has membrane bound organelles and is more complex
What are eukaryotic cells?
200
phase of mitosis where the cell is separating and contains two copies of each chromosome.
What is telophase?
200
Name the type of organic molecule known as fats
What are lipids?
200
component of the cell membrane that contains a hydrophobic region and acts as the primary barrier to most foreign substances
What is the phospholipid bilayer?
200
polar bears floating on ice floes to hunt for food is an example of this property
What is density?
200
helps a cell to keep its shape
What is cytoskeleton?
300
phase of mitosis where chromosomes separate into chromatids and the chromatids move to opposite poles
What is anaphase?
300
what happens to an enzyme when the temperature increases
What is the enzyme will change shape and no longer speed up the reaction?
300
movement of water molecules across a membrane
What is osmosis?
300
the bond between water molecules that is responsible for the property of cohesion
What is a hydrogen bond?
300
one type transports proteins and the other type produces lipids
What is the endoplasmic reticulum?
400
main difference between mitosis and meiosis
What is mitosis produces two genetically identical daughter cells?
400
how do enzymes affect the reactions in living cells
What is changes the speed of the reaction?
400
moves molecules from a high concentration to a low concentration and down the concentration gradient
What is passive transport?
400
since water is polar, name the slight charge that oxygen has and the slight charge hydrogen has
What are oxygen is negative and hydrogen is positive?
400
contains chlorophyll and participates in photosynthesis
What is a chloroplast?
500
Pairing of homologous chromosomes during meiosis I
What is synapsis?
500
if poison bonds to an enzyme what function will the enzyme be unable to perform
What is catalyze the reaction with the substrate?
500
moves molecules against their concentration gradient from a low concentration to a high concentration
What is active transport?
500
type of bond between the oxygen and hydrogen that make up water. It causes the oxygen and hydrogen to share electrons.
What is a covalent bond?
