Answers 100 % Correct [Grade A]
What do ligands do in general expression - correct answer They may alter the
transcription process
Signaling begins when an extracellular ligand binds to a ________ anchored in the
plasma membrane. ________ molecules and scaffolding proteins transduce the signal to
activate a cellular response - correct answer Receptor and Relay
What do Calera bacteria exotoxins bind to that cause permanent activation? - correct
answer GPCR
What happens first when signaling ligands to the extra cellular binding region of an
RTK - correct answer Dimerization of individual monomers
Signaling cell is considered - correct answer pre-synaptic
,The receiving cell is considered - correct answer Post-synaptic
How do mitochondrial proteins induce apoptosis - correct answer When mitochondrial
proteins are activated, there are pores which cause a leak in the membrane which
ultimately induces apoptosis
True or false; once a target cell has been restored to its inactive state, it can no longer
bind to a ligand. - correct answer False; once it has been restored to its inactive state,
it is primed and ready to bind to another one
True or false; scaffolding proteins, add phosphates to target sell receptor sites - correct
answer False; they support other proteins and improve efficiency in the transduction
pathway
What is matter? - correct answer Anything that takes up space,by having a volume,
and has mass

, Primary:
Secondary:
Tertiary:
Quarternary: - correct answer Primary: order in which amino acids are arranged in a
polypeptide chain
Secondary:includes repeating patterns
Tertiary: 3- dimensional shape
Quarternary: when 2 or more chains react
selective permeability - correct answer Ability or certain substances to move through
the cell membrane while others can't
