which have </span>chlorophylls<span>. With the presence of </span>sunlight and chlorophylls,<span> organisms which can do photosynthesis produce </span>glucose and oxygen<span> <span>as
products by using </span></span>carbon dioxide and water <span>as materials. </span>
Reaction is
6CO</span>₂(g) + 6H₂O(l) → C₆H₁₂O₆(s) + 6O₂<span>(g)</span>
Answer:
Red blood cells are considered cells, but they lack a nucleus, DNA, and organelles like the endoplasmic reticulum or mitochondria. Red blood cells cannot divide or replicate like other bodily cells. They cannot independently synthesize proteins,The nucleus is the cell's brain which controls much of its functions. An animal cell or eukaryotic cell will therefore die without a nucleus. The cell would not know what to do without a nucleus and there would be no cell division. The synthesis of proteins will either stop or shape wrong proteins.When red cells die, hemoglobin is broken up: iron is salvaged, transported to the bone marrow by proteins called transferrins, and used again in the production of new red blood cells
Explanation:
This pertains to the structure of proteins. Secondary structures are stabilized by the presence of hydrogen bonds. The common types of secondary structures of proteins are the alpha helix and the beta sheets, each performing different functions.
Primary structure of protein is the peptide molecule comprised of peptide bonds. Once these peptide grows long enough, it will either be arranged into alpha helices or beta sheets stabilized by hydrogen bonds and this is the secondary structure. Once there is protein folding involved in the secondary structure of protein, then the folded protein is called the tertiary structure (or a protein subunit). When protein subunits come together to perform a specific function, then that is the quaternary structure.
Attached is a figure concerning the protein structures.
