Phosphofructokinase is an allosteric enzyme in the pathway that breaks down glucose to produce ATP. Regulation of glycolysis is
directly related to the level of ATP and citrate. If ATP or citrate levels are high, phosphofructokinase is inhibited. What will happen to this enzyme when ATP levels drop?
Phosphofructokinase (PFK-1) is an enzyme of glycolysis that catalyzes the phosphorylation of fructose 6-phosphate to fructose 1,6-bisphosphate. The enzyme uses ATP as a phosphate group donor for this phosphorylation. It is a regulatory enzyme and the reaction catalyzed by it is irreversible. The activity of PFK-1 is increased whenever the cell’s ATP supply is depleted or when the ATP breakdown products, ADP and AMP, are in excess.
Tilling agitates the topsoil and removes ‘unnecessary’ vegetation so the main crop can grow without competition. Tilling improves soil aeration and drainage for plants to grow well. Nonetheless, it can lead to other consequences such as soil erosion because it loosens the soil and makes it easy to be carried away by wind and water.
Ligament injuries create disruptions in the balance between joint mobility and joint stability, causing abnormal force transmission throughout the joint resulting in damage to other structures in and around the joint.
Scientific inquiry when a student would find ideas and gather thoughts on a topic and think about it in depth. An example would be to gather ideas on how animals live in a certain park more than another.
The answer is <span>C) mosses, lichen, grasses, and small shrubs.
This is because mosses don't have roots and are very simple plants, therefore they don't have to "root" themselves into a permanently frozen ground that can't support them. </span>
