Cholecystokinin is a hormone secreted by the small intestine. It stimulates the secretion of pancreatic and bile juices. The presence of HCl,... View Article
Vmax is the maximum velocity of the reaction at which all the enzymes get saturated with the substrate. Km is the concentration of substrate at... View Article
Lactate dehydrogenase or LDH is an oxidoreductase enzyme present in the cytoplasm of the cell. It is involved in anaerobic respiration. Also... View Article
Lactate dehydrogenase (LDH) is an important enzyme of anaerobic cellular respiration. It catalyses the reversible conversion of pyruvate to... View Article
The main reason for high levels of hCG (human chorionic gonadotropin) is pregnancy. hCG is secreted by the placenta. Also Check: How Can The... View Article
Lactate dehydrogenase of lactic acid dehydrogenase (LDH) is an important enzyme of the anaerobic metabolic pathway. It converts pyruvate to... View Article
Lactate dehydrogenase is responsible for generating ATP when oxygen is absent. It continuously replenishes NAD+ from NADH, which is required for... View Article
At high atmospheric humidity, transpiration is low. This is because the transpiration rate is proportional directly to the saturation deficit.... View Article
When the movement of solute is limited compared to the water movement across the semipermeable cell membranes, water moves as per its chemical... View Article
DPD is the reason for the movement of water between cells. When a cell is dropped in pure water, it displays endosmosis, hence water enters the... View Article
Guttation is the loss of water via hydathodes (water stomata). This process takes place when the rate of transpiration is very low in comparison... View Article
The precipitation and temperature conditions in terrestrial regions are affected by transpiration. The pace of transpiration is directly... View Article
When sugar is converted into starch in guard cells, the stomatal pores completely close. During night time, carbon dioxide liberated during the... View Article
Always, water moves from low DPD to high DPD. Solutes and water enter through the root hair during absorption of water by roots. Once water is... View Article
Root tips mainly absorb water from soil. The two independent mechanisms involved in water absorption in plants are active and passive water... View Article
Movement of solutes or organic food from one to another structure in the soluble form is the translocation of solutes. For instance, from leaves... View Article
In pure water, chemical potential or water potential is arbitrarily zero bar. Solute potential or osmotic potential indicates the impact of the... View Article
Water occurs in the following different forms in the soil - gravitational water, free water, hygroscopic water, capillary water and chemically... View Article
Zelitch proposed that glycolic acid takes form in the guard cells. It is formed under the influence of low concentration of carbon dioxide.... View Article
The rate of salt absorption increases when the temperature increases. However, this is to some limit as absorption of salt is hindered at high... View Article
