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...

Test Bank for Abnormal Psychology An Integrative Approach 8th Edition By David H. Barlow Page 1 WWW.NURSINGTESTBANKSWORLD.COM 1. Psychological abnormality is generally defined using “the four D's.” First, explain what the four Ds are and what they mean regarding psychological abnormality. Then provide an example of a time when each aspect of abnormality would not be considered abnormal. 2. Suppose a friend says to you, “I feel really lousy today, and I don't know why. You're ...

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 ...

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...
