So how are the cells are arranged to form a solid structure a solid body?
Plant cells have cell walls, are filled with liquid, and have strong cell-cell adhesion. This gives a fairly rigid structure that may seem like a solid. Take a carrot for example, it seems solid. But if you put the carrot in a blender, you get carrot juice - not a solid. Also, when ...

1) Is the process of hydrolysis that breaks up polypeptides and polysaccharides a net endothermic or exothermic process?
Under physiological conditions, it is a process that goes forward, i.e. the Gibbs energy is negative. As a consequence, it can happen outside of cells in the absence of ATP. When we eat, the hydrolysis of polysaccharides starts in our ...

If you are a using reversed-phase (RP) column, it is okay to directly inject your crude sample in the running HPLC solvent system. But, make sure to filter the injecting sample through a membrane filter to remove minute particles (from glass beats, etc.) from the original sample after dissolving it in suitable chosen solvent. Please also note that your ...

Biologically, methane is produced by methanogens, which are Archeabacteria. They do not utilize carbohydrates such as cellulose or glucose directly. Instead, they typically consume acetate or a mixture of hydrogen gas and carbon dioxide. These stoichiometry of these two processes is
$\ce{4H2 + CO2 -> CH4 + 2H2O}$ or
$\ce{CH3C(O)OH -> CH4 + CO2}$.
To ...

Peptide bonds are rigid and planar in nature and Ramachandran plots are used to analyze protein structures and predict stable amino acid conformations in the protein.
A Ramachandran plot is a method to visualize energetically stable regions for polypeptide torsion angles psi (ψ ) against (phi) φ of amino acid residues present in a protein structure.
A ...

Why Molybdenum is Used in the Manufacture of Ammonia?
Molybdenum tubing has particularly good resistance to corrosion by
mineral acids, provided oxidizing agents are not present. It is also
resistant to many liquid metals and to most molten glasses. Molybdenum
is relatively inert in hydrogen, ammonia, and nitrogen up to about
1100 C, but a ...
