Intro to Science
The study of life
What is Biology?
Subatomic particles found outside the nucleus of an atom
What is an electron?
One difference between eukaryotic and prokaryotic cells
nucleus vs no nucleus, size, single celled vs multi celled, need O2 vs no need for O2, and organelles vs no organelles
A + B => C + D. Identify the reactant.
A and B
The capacity to do work
What is energy?
The largest level of organization
Atomic number = number of which subatomic particle
what is protons?
Chloroplasts and cell walls are found in this cell type
what is a plant cell
Define catabolic reactions
breakdown of larger molecules to smaller ones
In a saltwater solution. What is the solute and what is the solvent
solute-salt
solvent-water
The smallest level of organization
Amino acids are monomers of which biomolecule
What is a protein?
The function of the golgi apparatus
process and package proteins
Define oxidation AND reduction
oxidation = lose electron
reduction = gain electron
Which subatomic particles make up atomic mass
What is protons and neutrons
A general set of principles supported by data, based on numerous studies
What is a theory?
Nonpolar covalent bonds are different from polar covalent bonds in this way.
nonpolar = electrons shared equally
polar = electrons shared unequally
The function of lysosomes
contains enzymes that degrade debris
Endergonic vs exergonic
endergonic = requires energy
exergonic = releases energy
The 3 statements of cell theory
1) cells are basic unit of life, 2) living things are either made of one cell or many cells, 3) all cells come from other cells
List at least 5 of the 7 characteristics of living things
What is
1) use energy, 2) homeostasis, 3) highly organized, 4) evolution, 5) DNA, 6) reproduction, 7) made of cells
The four types of complex carbohydrates
What is starch, glycogen, cellulose and chitin
The 4 components of the plasma membrane (cell membrane)
made up of phospholipids, proteins, cholesterol, and glycolipids/glycoproteins
The difference between the lock and key model vs the induced fit model
lock and key - substrate matches active site
induced fit - enzyme goes through temporary change
List 2 metabolic reactions and whether they are catabolic OR anabolic
hydrolysis-catabolic, condensation-anabolic, phosphorylation-anabolic, and dephosphorylation-catabolic
