After reading this article you will learn about: 1. Phloem Sap Composition 2. Movement in Phloem Sap. Phloem Sap Composition: The major phloem sap components are carbohydrates. Analyses of the phloem exudates from various plants have shown that sucrose is the major transportable form of carbohydrate. In some species of Cucurbitaceous, in addition to sucrose, certain oligosaccharides like raffinose, stachyose, [...]
The following points highlight the top four types of assays of enzymes. The types are: 1. Amylase 2. Urease 3. Catalase 4. Peroxidase. Assay of Enzyme: Type # 1. Amylase: Amylases are hydrolyzing enzymes which catalyze the hydrolysis of starch through the addition of elements of water to α (1 → 4) glycosidic linkage. The product of enzymic hydrolysis of [...]
In this article we will discuss about Phloem Transport. After reading this article you will learn about: 1. Mechanism of Phloem Transport 2. Factors Affecting Phloem Transport. Mechanism of Phloem Transport: The mechanism of long-distance transport through the sieve tube is soundly based on the internal organization of sieve tubes, without which it remains speculative. Phloem tissue is composed of [...]
