Prince Kundu 1 year, 9 months ago

Alycosidic bonds are formed between peptides and proteins. Peptide bonds are also formed between proteins and phospho- diesters. These bonds are important for the stability of proteins and can play a role in the function of proteins.

Human heart

Posted by Sadaf Ulaain 1 year, 10 months ago

CBSE > Class 11 > Biology

1 answers

Preeti Dabral 1 year, 10 months ago

Structure of Human Heart

The heart is a muscular organ covered by a double membrane called pericardium.
The pericardial fluid of the pericardium lubricates the heart.
The heart is divided into four chambers — two upper atria and two lower ventricles.
The inter-atrial septum separates the two atria and the inter-ventricular septum separates the two ventricles.
The atrium and the ventricle of each side are separated by the atrioventricular septum.
Superior and inferior vena cavae open into the right atrium.
The right ventricle opens into the pulmonary artery.
Four pulmonary veins open into the left atrium.
The left ventricle opens into the aorta.
The opening between the right atrium and right ventricle is guarded by the tricuspid valve.
The opening between the left atrium and left ventricle is guarded by the bicuspid (mitral) valve.
The opening of the right ventricle into the pulmonary artery and the opening of the left ventricle into the aorta is guarded by the semilunar valves.

Working of Heart

The right atrium receives blood from the upper and lower body through the superior vena cava and the inferior vena cava, respectively, and from the heart muscle itself through the coronary sinus. The right atrium is the larger of the two atria, having very thin walls. The right atrium opens into the right ventricle through the right atrioventricular valve(tricuspid), which only allows the blood to flow from the atria into the ventricle, but not in the reverse direction.
The right ventricle pumps the blood to the lungs to be reoxygenated.
The left atrium receives blood from the lungs via the four pulmonary veins. It is smaller than the right atrium but has thicker walls. The valve between the left atrium and the left ventricle, the left atrioventricular valve(bicuspid), is smaller than the tricuspid. It opens into the left ventricle and again is a one-way valve.
The left ventricle pumps the blood throughout the body through the aorta, which is the largest artery in the body. The walls of the left ventricle are the thickest among all the chambers.

Define photorespiration

Posted by Richa Desai 1 year, 10 months ago

CBSE > Class 11 > Biology

1 answers

Preeti Dabral 1 year, 10 months ago

In C₃ plants some O₂ does bind to RuBisCO, and hence CO₂ fixation is decreased. Here the RuBP instead of being converted to 2 molecules of PGA binds with O₂to form one molecule and phosphoglycolate in a pathway called photorespiration. In the photorespiratory pathway, there is neither synthesis of sugars, nor of ATP. Rather it results in the release of CO₂with the utilization of ATP. In the photorespiratory pathway, there is no synthesis of ATP or NADPH. Therefore, photorespiration is a wasteful process.

Pravisha Shukla 1 year, 11 months ago

This pathway was worked out by Hatch and Slack (1965, 1967), mainly operational in plants growing in dry tropical region like Maize, Sugarcane, Sorghum etc. In this pathway first stable product is a 4-carbon compound Oxaloacetic acid (AAO) so called as pathway. plants have Kranz Anatomy (vascular bundles are surrounded by bundle sheath cells arranged in wreath like manner), characterized by large no of chloroplast, thick wall impervious to gases and absence of intercellular spaces. The primary acceptor is a 3-carbon molecule Phosphoenol Pyruvate present in mesophyll cells and enzyme involved is PEP carboxylase. OAA formed in mesophyll cell forms 4-carbon compound like malic acid or aspartic acid which is transported to bundle sheath cells. In bundle sheath cell, it is broken into and a 3-carbon molecule. The 3-carbon molecule is returned back to mesophyll cells to form PEP. The molecules released in bundle sheath cells enters the Calvin cycle, where enzyme RuBisCO is present that forms sugar.
