Hey all I am trying to create a data base but I am having some issues. My below code is running but it is only pulling the last enzyme glucose-6-phosphate dehydrogenase into the table (and its subunits, etc.) and I am not sure why. Any help would be appreciated, thanks!

#creating connection to my.db
conn = sqlite3.connect ('my.db')
c = conn.cursor()

#creation of genes table
c.execute("""CREATE TABLE genes (id INTEGER PRIMARY KEY AUTOINCREMENT, symbol TEXT, name TEXT, description TEXT, n_sequence TEXT)""")
#creation of pathways table
c.execute("""CREATE TABLE pathways (id INT, name TEXT, description TEXT)""")
#creation of enzymes table
c.execute("""CREATE TABLE enzymes (id INT, name TEXT)""")
#creation of association table between genes and enzymes
c.execute("""CREATE TABLE genes_and_enzymes (gene_id INT, enzyme_id INT)""")
#creation of association table between enzymes and pathways
c.execute("""CREATE TABLE enzymes_in_pathways (enzyme_id INT, pathway_id INT)""")



#commitment for new tables
conn.commit()

#next 3 lines are inserting rows into pathways and their description
c.execute("""INSERT INTO pathways (id, name, description) VALUES (1, "glycolysis", "the catalysis of glucose");""")

c.execute("""INSERT INTO pathways (id, name, description) VALUES (2, "TCA", "cyclic pathway");""")

c.execute("""INSERT INTO pathways (id, name, description) VALUES (3, "PPP", "generates NAD(P)H and pentose sugars");""")
