What happened to glucose if it is breakdown in the cell in the presence of O2 and lack of oxygen it is 5 mark questions

Posted by Bhumika Agrawal 5 years, 11 months ago

CBSE > Class 10 > Science

1 answers

??Geetha Sree ?? 5 years, 11 months ago

In any situation the first step is the breaking down of glucose(6 carbon molecule) into pyruvate(3 carbon molecule) . Then in the presence of O2 it takes place in mitochondria. It is known as aerobic respiration. In this process the pyruvate further breaks down into CO2 + H2O + energy. Then in the lack of O2 it takes place in our muscle cells. Secretion of lactic acid takes place. In this the pyruvate further breaks down into lactic acid + CO2 + energy. This causes sudden cramps in our muscle cells.

What are the different type of Asexual Reproduction explain each type type of asexual reproduction example

Posted by Bhumika Agrawal 5 years, 11 months ago

CBSE > Class 10 > Science

1 answers

Meghna Thapar 5 years, 10 months ago

Various methods of asexual reproduction are: i. Binary Fission - Fission in which the parent cell divides to form two similar daughter cells. Example - Amoeba. ii. Multiple Fission - Fission in which the parent cell divides to produce more than two daughter cells. Example - Plasmodium. iii. Budding - The reproductive method in which an organism produces an outgrowth on its body surface, which then matures and develops into a new individual. Example - Hydra. iv. Spore Formation - Spore formation is an asexual mode of reproduction found in certain multicellular organisms like Rhizopus. The thick walled spores have the capacity to develop into new individuals under suitable conditions. v. Regeneration - Regeneration is found in many completely differentiated simple organisms, like Hydra and Planaria. If such an organism is split into several parts, most of the parts will develop into complete organisms. vi. Fragmentation - The reproductive method in which certain multi-cellular organisms, on maturation, break up into smaller fragments, each of which develops into new individual. Example - Spirogyra.

Describe the nutrition in amoeba

Posted by Bhumika Agrawal 5 years, 11 months ago

CBSE > Class 10 > Science

1 answers

Meghna Thapar 5 years, 10 months ago

Nutrition in Amoeba: The mode of nutrition in amoeba is holozoic. Nutrition in amoeba involves the following steps (i) Ingestion – Amoeba has no mouth for ingestion of food. It ingests the food by using its pseudopodia. The food is engulfed with little water to form a food vacuole. (ii) Digestion – The food is digested by digestive enzymes present in the cytoplasm which breaks the food into small soluble molecules by chemical reactions. (iii) Absorption – The digested food is absorbed directly into the cytoplasm by diffusion. The digested food spreads out from the food vacuole into the whole cell and after absorption the food vacuole disappears. (iv) Assimilation – Food is used to obtain energy through respiration and the remaining part of the food is used for growth. (v) Egestion – The undigested food collects inside the cell and the cell membrane ruptures. Through this, the undigested food is thrown out of the body.

The addition of hydrogen to an unsaturated hydrocarbon to obtain a saturated hydrocarbon is called hydrogenation. When a vegetable oil (like groundnut oil) is heated with hydrogen in the presence of finely divided nickel as catalyst, then a saturated fat called vegetable ghee (or vanaspati ghee) is formed. This reaction is called hydrogenation of oils.
