Ultimate AP Biology Exam Review Questions with Verified Answers Compare and contrast transpiration and translocation. What is the difference between xylem and phloem? Tranpspiration is the loss of water vapor from the surgace of a plant through the stomata. Translocation is the channeling of the sugar through the phloem. Define hypoosmotic, hyperosmotic, and isomotic 1. Has a lower concentration of solutes than its surrounding enviorment 2. Has a higher concentration of solutes than i...

Biochemistry Final Exam Questions and Answers Already Passed What role do protein domains play in enzyme function? Protein domains allow enzymes to perform specific functions, often facilitating interactions with other molecules or substrates. How do post-translational modifications affect protein behavior? They can alter protein activity, localization, and stability, enabling dynamic responses to cellular signals. What is the significance of the "lock and key" model in e...

(T/F) A biochemical reaction, without a catalyst or thermodynamic coupling, takes 50 years to reach a state of equilibrium. Without more information, we cannot make a determination on either the value of the Keq constant or the positive or negative value of the ΔG of the reaction. Correct Answer-False (T/F) Due to its small size, the amino acid glycine can be found in tight turns in a protein structure. Correct Answer-True (T/F) The ΔG of a reaction is defined as the energy required to b...

How does information flow? From DNA to RNA to protein What information is central to modern biotechnology? The use of methods to study and manipulate information about the central dogma. What is the exception to the central dogma? The transcription of RNA into DNA using reverse transcriptase. How does the cycle of the central dogma work? Instructions of DNA are transcribed onto messenger RNA. The ribosomes are able to read the genetic information inscribed on a strange of the ...

Biochemistry Test 1 Questions and Answers Graded A+ What is the role of allosteric sites in enzyme regulation? Allosteric sites are regions where molecules can bind and influence enzyme activity by changing its shape. How do competitive inhibitors affect enzyme function? Competitive inhibitors compete with substrates for binding at the active site, reducing enzyme activity. What determines the tertiary structure of a protein? The tertiary structure is determined by interactio...

What is the basic structure of an amino acid? What do they look like? - amino group (NH2 or NH3), carboxyl group (COO or COOH), alpha carbon (C), and variable group How do you identify the 3 different types of side chains: non-polar/hydrophobic, polar, and charged? - Non-polar/hydrophobic - end with CH or "can't have" water. Polar - end with OH, SH, or NH. Charged - end with a charge what kinds of bonds do each of the 3 different types of side chains make? - ionic, hydrophobic/non- pola...

Electronegativity of water correct answers The different electronegativities of hydrogen and oxygen make water a polar molecule capable of forming hydrogen bonds. This makes water a good solute. Hydrophobic interactions correct answers Non-polar hydrophobic compounds dissolve poorly in water. These compounds minimize their surface area exposed to water by forming aggregates in which the hydrophobic groups go to the interior through hydrophobic interactions. Only the more polar portions intera...
