QuestionAnswer
Adenosine Triphosphate is a nucleotide
Which of the following is not a form of energy? Heat, diffusion, sound, light, gamma radiation. Diffusion
The ultimate fate of the energy used by organisms is to be converted into heat
According to the first law of thermodynamics, energy only changes forms
During every energy transformation, it can be said that the entropy of the universe increases.
Identify the exergonic reaction in the list below burning wood for a campfire
In a system in which temperature is uniform, free energy is the energy available to do work
When a reaction reaches equilibrium the rate of the forward and reverse reactions are equal
Metabolic pathways can be either catabolic or anabolic
The term that best describes all of the chemical reactions of the cell, including acquisition and use of molecules and energy, is metabolism.
When there are more reactants than products for a reaction, the greater concentration of reactants pushes the reaction forward, toward generating more products
True or False Hydrolysis of ATP is used to drive all of the following reactions in a cell: active transport of solute, catabolic reactions, protein activation., phosphorylation of target proteins True
When ATP is split into ADP and Pi, the binding of ADP or Pi to the target molecule allows the energy of ATP hydrolysis to be transferred to the target molecule
The coupling of endergonic to ____ reactions is used to generate ____ in a cell. exergonic, ATP
What type of reaction produces less free energy than the reactants exergonic
What changes the rate of a reaction Enzymes
In competitive inhibition the inhibitor binds to and directly blocks the active site of the enzyme
In noncompetitive feedback inhibition the products of the reaction at the end of the pathway bind to a site other than the active site of an enzyme at or near the beginning of the pathway and block enzyme activity indirectly
The cofactors required for enzyme activity often are allosteric activators.
The difference between cofactors and coenzymes is that cofactors can be inorganic or organic, coenzymes are just another name for organic cofactors.

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.
