Question

Steroid hormone response elements (HREs) are ___, which, when bound by a ___, alter gene expression at the level of ___. intron sequences, activated hormone receptor, translation nuclear proteins, hormone, transcription plasma membrane proteins, hormone, transcription sequences in DNA, receptor-hormone complex, replication sequences in DNA, receptor-hormone complex, transcription The citric acid cycle enzymes, isocitrate dehydrogenase and alpha-ketoglutarate dehydrogenase, in muscle cells are activated by increased levels of Ca2+. These important regulatory enzymes are inhibited by what allosteric effectors? Citrate, Coenzyme A (CoA-SH) ATP, NADH ADP, AMP NAD+, FAD Acetyl-CoA. FADH2

Explanation / Answer

22. The correct option is 2. Steroid hormone response elements are nuclear proteins, which are bound by the hormone, and alter gene expression at the level of transcription.

23. The correct option is 2. ATP and NADH allosterically inhibit these two enzymes.  NADH inhibits iso-citrate dehydrogenase by directly displacing NAD+. ATP is also inhibitory.
