Given  some  statements  about auxin  signal  transduction  pathway;
a) ARFs bind the AuxRE stably, must form dimers promote transcription by binding to two AuxREs arranged in a palindrome
b) inactive heterodimers may act to inhibit ARF–AuxRE binding, thereby blocking either gene activation or repression
c) Protein encodes the AUX/IAA gene family can inhibit the transcription of early auxin response genes by forming inactive heterodimers with ARFs
d) Auxin induces the transcription of the early response genes by promoting the proteolytic degradation of the inhibitory AUX/IAA proteins so that active ARF dimers can form
e) AUX/IAA turnover to involve ubiquitination by a ubiquitin ligase and proteolysis by the massive 26S proteasome complex
f) A negative feedback loop is introduced into the pathway by virtue of the fact that one of the gene families turned on by auxin is AUX/IAA, which inhibits the response.
Find out the correct sequence from the following above statements;

The following statements are related to pentose phosphate pathway.

a) The first and third steps are oxidations with large, negative standard free-energy changes and are essentially irreversible in the cell

b) NADPH rises and inhibits the first enzyme in the pentose phosphate pathway. As a result, more glucose 6-phosphate is available for glycolysis

c) All the enzymes of the reversible reaction of the pentose phosphate pathway are located in the cytosol

d) The NADPH is used for biosynthetic reactions such as lipid synthesis and nitrogen assimilation in the cytosol
