IEOC BIO - Sheet1 Flashcards
______________ STORE AND TRANSMIT HEREDITARY, OR GENETIC INFORMATION.
nucleic acids
What is the function of ribosomes?
To make protein (protein synthesis)
WHAT ARE THE LEVELS OF ORGANIZATION (largest to smallest)
biosphere, ecosystem, community, population, organism, groups of cells, cells, and molecules
THE ENERGY NEEDED TO GET A REACTION STARTED IS CALLED THE:
Activation Energy
WHAT DOES AN ENZYME DO?
Speed up the rate of a chemical reaction by lowering activation energy
TRUE OR FALSE-ENZYMES WORK AT EVERY TEMPERATURE?
false-slow down at lower temperatures or too high of temperatures
THE FOUR GROUPS OF ORGANIC COMPOUNDS ARE:
carbohydrates, lipids, proteins, and nucleic acids
WHAT ORGANIC GROUP IS THE MAIN SOURCE OF ENERGY FOR HUMANS.
carbohydrates
_______________ ARE USED TO STORE ENERGY, AND ARE IMPORTANT PARTS OF BIOLOGICAL MEMBRANES.
lipids
______________ STORE AND TRANSMIT HEREDITARY, OR GENETIC INFORMATION.
nucleic acids
What is the function of ribosomes?
To make protein (protein synthesis)
WHAT ARE SOME CHARACTERISTICS OF ENZYMES?
They work best at a specified pH, they are temperature dependent, they are proteins, they can be denatured.
_________ SPEED UP CHEMICAL REACTIONS THAT TAKE PLACE IN CELLS.
enzymes
______________ ALLOWS CELLS TO PERFORM DIFFERENT FUNCTIONS.
cell specialization
The cell organelle in charge of storage?
VACUOLE
Which organelles split themselves in 1/2 to digest dead cells or cell invaders?
LYSOSOMES
Which organelle rips the cell apart during cell division?
CENTRIOLES
What organelle is the cell boundary?
CELL MEMBRANE
What 2 organelles are found in a plant cell, but not an animal cell?
CHLOROPLASTS AND CELL WALL
What gives a cell its shape?
CELL MEMBRANE AND WATER
What is the name for a cell that does not have a nucleus?
PROKARYOTE
What is the name for a cell that does have a nucleus?
EUKARYOTE
What is the smallest unit of life?
CELL
The process in which molecules move from an area of large concentration to an area of low concentration is:
DIFFUSION
Diffusion through a semipermeable membrane is called:
OSMOSIS
The concentration of solutes is the same on both the inside and the outside of a cell.
ISOTONIC
The concentration of solutes is greater outside of the cell, causes the cell to dry out.
HYPERTONIC
The concentration of solutes is greater inside the cell.
HYPOTONIC
A single-celled organism. Bacteria falls into this category.
UNICELLULAR
Organisms made up of many cells are classified as this:
MULTICELLULAR
An energy-requiring process that moves material across a cell membrane.
ACTIVE TRANSPORT
The organelle in a cell that in charge of packaging and sorting proteins.
GOLGI APPARATUS
Which organelle provides the cell with energy?
MITOCHONDRIA AND CHLOROPLASTS
What is the jellylike material that holds the organelles?
CYTOPLASM
What is the control structure of the nucleus?
NUCLEOLUS
The highway of the cell in charge of cell that transports materials.
ENDOPLASMIC RETICULUM
What is the main function of the cell wall?
SUPPORT AND PROTECTION
What is the main function of the cell membrane?
REGULATES WHAT ENTERS AND LEAVES THE CELL
