Question

Explain where the energy for each step comes from and what other proteins are involved.

can u tell me please its a 7 marks

Draw the generalized structure of a ribosome and label the major feature ( this is the topic )

and rest is based on this question

I guess ribosomal steps

Answer 1

The process might be the process of protein synthesis that is Translation

Figure of Ribosome:-

The energy :-
The energy for the process is from the GTP-GDP hydrolysis pathway. The GTP-GDP hydrolysis not only causes the conformatonal changes during the process but also helps i activation of certain proteins that aid in the shifting process of the mRNA and the codons.

The proteins involved:-

IF-1	Assists IF-3
IF-2	inding initiator tRNA and GTP
IF-3	Releases mRNA and tRNA from recycled 30S subunit
EF-Tu	Binds aminoacyl-tRNA and GTP
EF-Ts	Displaces GDP from EF-Tu
EF-G	Promotes translocation through GTP binding and hydrolysis
Release factors1,2,3	Recognizes stop codons and releases themselves after functions
RRF	Together with EF-G induces ribosomal dissociation
