c (a) and (b) are the two cellular organelles in eukaryotes that have both electron transport chains ( (c) ).
Which of the following would best describe anabolism?
This metabolic pathway is a constructive (building) pathway which means it needs ATP.
This metabolic pathway is a degradative (breaks down) pathway which means it generates ATP.
This metabolic pathway is a degradative (breaks down) pathway which means it needs ATP
This metabolic pathway is constructive (building) pathway which means it generates ATP.
Reorder the following by how many phosphates it has.
AMP
ADP
ATP
What is the primary function of ATP in cellular processes?
To store genetic information
To provide structural support for cells
To facilitate energy coupling and power cellular processes
To act as a catalyst for chemical reactions
A researcher proposes a model of an enzyme-catalyzed reaction in which a reactant is converted to a product. The model is based on the idea that the reactant passes through a transition state within the enzyme-substrate complex before the reactant is converted to the product. Which of the following statements best helps explain how the enzyme speeds up the reaction?
The enzyme’s active site binds to and stabilizes the reactant, which decreases the free-energy change of the reaction.
The enzyme’s active site binds to and stabilizes the transition state, which decreases the activation energy of the reaction.
The enzyme’s active site binds to and stabilizes the product, which increases the amount of energy released by the reaction.
The enzyme’s active site binds to and stabilizes both the reactant and the product at the same time, which increases the reaction’s equilibrium constant.
(a) Law of Thermodynamics says (b) but (c) . (d) Law of Thermodynamics says (e) .
A researcher claims that increased atmospheric carbon dioxide levels cause increased growth rates in plants. Which of the following statements best supports the researcher’s claim?
Atmospheric carbon dioxide is produced by the burning of fossil fuels, which are formed from the remains of living organisms such as plants.
Atmospheric carbon dioxide is a byproduct of cellular respiration, which is a metabolic process that occurs in plants and other living organisms.
Atmospheric carbon dioxide typically enters plant leaves through stomata, which plants rely on for regulating gas exchange with the atmosphere.
Atmospheric carbon dioxide is the raw material for photosynthesis, which plants rely on for producing sugars and other organic compounds.

Pyruvate dehydrogenase is an enzyme that converts pyruvate to acetyl-CoA. Acetyl-CoA is further metabolized in the Krebs cycle. A researcher measured the accumulation of acetyl-CoA in a reaction containing pyruvate and pyruvate dehydrogenase under several different conditions. Which of the following best describes the cellular location where pyruvate dehydrogenase is most likely active?
The cytosol
The lysosomes
The nucleus
The mitochondrial matrix
