Virions are composed largely of nucleic acids and protein. In order to produce more virions, the host cell must synthesize more of these parts through NA replication and protein synthesis.
Answer;
Glucose
The nutrient that can be used to produce energy in the absence of oxygen is glucose.
Explanation;
Production of energy without using glucose is called anaerobic respiration. During this type of respiration less energy is released than the case of aerobic respiration. This is because the breakdown of glucose is incomplete. Anaerobic respiration produces an oxygen debt, which is the amount of oxygen needed to break lactic acid to carbon dioxide and water.
On the basis of information in the paragraph above, the eggs should be able to be observed in Tp. Trichoplax adhaerens is the only extant representative of phylum Placozoa, which is a basal group of multicellular animals. Trichoplax are very flat organisms around a milimetre in diameter, lacking any organs or internal structures. They have two cellular layers, the top epitheloid layer is made of ciliated "cover cells" flattened toward the outside of the organism, and the bottom layer is made up of cylinder cells that posses cilia used in locomotion, and gland cells that lack cilia.
Answer:
Phosphofructokinase-1
Explanation:
Phosphofructokinase-1 catalyzes the phosphorylation of fructose 6-phosphate into fructose 1,6-bisphosphate. The reaction is exergonic with a large negative free energy change to make it essentially irreversible.
Phosphofructokinase-1 is an allosteric enzyme with regulatory sites. Higher ATP concentration serves to inhibit the phosphofructokinase-1 by binding to the allosteric site of the enzyme and thereby reducing its affinity for the substrate (fructose 6 phosphate).
