2024 AQA AS BIOLOGY 7401/1 Paper 1 Question Paper & Mark scheme (Merged) June 2023 VERIFIED / Biology AQA AS level 7401/1 Paper 1 Describe the induced-fit model of enzyme action - ANSWER-- active site not complementary to/does not fit substrate - Shape of active site changes as enzyme- substrate complex forms - Distorting bonds (in substrate leading to reaction) • The human cell then makes a complementary strand to the HIV DNA. The complementary strand is made in the same way as a ne...

HESI A2 ENTRANCE EXAM: READING COMPREHENSION, CHEMISTRY, GRAMMAR, BIOLOGY, VOCABULARY & GENERAL KNOWLEDGE, CRITICAL THINKING, ANATOMY & PHYSIOLOGY AND MATH VERSION 2 (With answers) Reading Comprehension Neurologists and biological psychologists have witnessed a sharp increase in the knowledge and understanding of particular structures of the brain over the past two decades. As technology becomes ever more advanced, scientists are able to isolate the functions of even small regions of ...

AQA A LEVEL BIOLOGY PAPER 1 2021. Describe the induced-fit model based on enzyme action and how an enzyme acts as a catalyst. [3 marks] . 2 Scientists investigated the action based on the enzyme ATP synthase. They made reaction mixtures each containing: • ATP synthase • buffer (to control pH) • substrates. One based on the substrates required within these reaction mixtures is inorganic phosphate (Pi). Tick ( ) one box to show which other substrate the scientists must add to the ...

Biology 1201 LSU Exam 2 Questions and Answers 100% Pass What type of chemical reaction is without outside energy? Spontaneous (exergonic/downhill) NOT INSTANTANEOUS -decreasing enthalpy and increasing entropy What is the equation for Free Energy? deltaG=deltaH-TdeltaS -free enrgy=enthalpy-(temp.)(entropy;disorder) -high deltaS=low delta G Entropy Disorder: -breakdown: increase in disorder, more parts -synthesis: decrease in disorder, less parts -high entropy=low free energy ...

Amino Acid and Side Groups correct answers - Negative Side Groups = Acidic - Positive Side Groups = Basic Absolute Configuration correct answers refers the R/S naming convention. Some amino acids are R, and some are S. Relative Configuration correct answers - D/L naming convention. - All biologically produced amino acids are in the L configuration. Conformational stability correct answers - Temperature: Denatures second, third, and fourth tertiary - pH: Third and fourth; Destroys io...

What is kcat? What is a holoenzyme? Correct Answer-Kcat=overall rate of an enzyme, catalytic efficiencies. Holoenzyme (active) is an inactive apoenzyme with non-protein components. (look at the picture) Discuss enzyme-substrate specificity. What is the lock and key vs. induced fit model? Correct Answer-Induced fit: enzyme changes after substrate binds to make it fit more perfectly. Discuss energy implications of enzymes. Does it change the activation energy or free energy of the overal...
