Stansel Bio A Unit 2

Biology A Unit 2 Test Stansel

QuestionAnswer
Transport proteins play a role in both passive and active transport
which process requires no energy from the cell facilitated diffusion
which process is occurring when a vesicle fuses with the cell membrane and releases its contents outside the cell? exocytosis
what molecule carries chemical energy that cells use for their functions? ATP
Chemosynthesis is a process through which some organisms use ___________________from their environment to build sugars they use for energy. chemicals
which of the following is a reactant in photosynthesis? oxygen
where in plant cells are the energy-absorbing molecules for photosynthesis located? chloroplasts
the part of the cellular respiration that needs oxygen takes place inside the mitochondria
which process is best represented by the following equation? sugars + oxygen =carbon dioxide + water cellular respiration
an electron transport chain that produces ATP is part of both the cellular respiration process and photosynthesis
in which process is lactic acid formed when there is not enough oxygen present for cellular respiration to take place? glycolysis
in order to begin cellular respiration, glucose must be broken down by the process of glycolysis
as a result of diffusion, the concentration of many types of substances eventually becomes balanced on both sides of a membrane
diffusion is the movement of a substance from an area of high concentration to an area of lower concentration
proteins that serve as tunnels for specific substances through the lipid bilayer are channel proteins
sugar molecules are larger and cross the cell membrane by facilitated diffusion
which of the following does not require energy? diffusion
the diffusion of water into or out of a cell is called osmosis
unlike passive transport, active transport requires energy
which of the following is a form of active transport? facilitated diffusion
proteins and polysaccharides that are too large to move into a cell through diffusion or active transport move in by endocytosis
molecules that are too large to be moved across a cell membrane can be removed from the cell by endocytosis
most of the energy used by life on earth comes from the sun
light energy is converted to chemical energy through the process of photosynthesis
ATP is composed of a nitrogeneous base, a sugar and 3 phosphate groups
When a phosphate group is removed from an ATP molecule, a substantial amount of energy is released
because of photosynthesis the atmosphere is rich in oxygen gas
the energy used in the Calvin cycle for the production of sugar molecules comes from ATP
when glycolysis occurs a molecule of glucose is split
what is the net gain of ATP molecues in glycolysis 2
which of the followoing is not part of cellular respiration Calvin Cycle
which of the follwoing is not formed during the Krebs Cycle? NADPH
Fermentation enables glycolysis to continue under anaerobic conditions
cells produce ATP most efficienly in the presence of oxygen
which of the following processess produces the most ATP aerobic respiration

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
