The actual process of chromatin remodeling in eukaryotic cells does not involve:

Out of the following given choices:

HDACs

DNA methylation.

protein kinase cascades.

Histone acetylation.

All of the above are involved in the process known as chromatin remodeling.

The answer is ‘All of the above are involved in the process known as chromatin remodeling’. Chromatic remodeling is critical in the regulation of genes on the chromosomes. DNA and histone methylation mostly cause the downregulation of genes due to their compaction hence unavailing them for transcription by RNA polymerases

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
