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...

AC-HPAT Prep (Biology, Chemistry, Physics, Math) 188 Questions With Complete Solutions. Most of the cell membrane's specific functions are controlled by: Proteins Alcoholic Fermentation is a form of: Anaerobic Respiration Phagocytosis is a form of: Endocytosis What is a pyruvate? Pyruvate is an important chemical compound in biochemistry. It is the output of the metabolism of glucose known as glycolysis. One molecule of glucose breaks down into two molecules of pyruvate, which are then...

The structure of a strand of DNA. - Answer-it is a double helix, like a twisted ladder. the ladder rings are nucleotide subunits and they have a covalent bond to the sugar phosphate backbone (made of deoxyribose and a phosphate group) What are the nucleotide subunits? - Answer-adenine, guanine, cytosine, and thymine How are the subunits held together? - Answer-through a hydrogen bond What are the nucleotide subunits compliments? - Answer-Adenine and thymine cytosine and guanine How does D...

TAMU bio 111 lab exam 2 review (2023/2024) already passed What is the difference between the coding and non-coding region? Coding region: comprised of genes that encode proteins (instructions that determine traits) and makes up 1-2% of human DNA. • Noncoding region: makes up 98-99% of human DNA, contains STRs and is responsible for regulatory functions such as gene transcription. What are STRs? Short-tandem repeats (STRs) are unique repeating patterns of the same nucleotide sequence. They can...

Bacterial Transformation Lab Report Title: Bacterial transformation lab Objective(s): The length of the time for which the heat shock is given greatly affects the process of transformation or the uptake of the plasmid by the bacterial cell. Hypothesis: As the length of the time of the heat shock increases there are greater chances of the process of transformation or the uptake of the plasmid by the bacterial cell. As the time period of heat shock increases, the bacterial cell membrane deve...
