ADRENAL GLAND

Adrenal glands are supra-renal glands which consists of two parts; cortex and medulla which releases certain hormones to regulate the process of human body. Read More >>>

THYROID AND PARATHYROID GLAND

Thyroid glands are located in our neck region and secretes thyroxine, TCT and calcitonin hormone. On the other hand Parathyroid gland is located on the posterior side of thyroid gland and release PTH. Read More >>>

PITUITARY GLANDS AND HORMONES

Pituitary gland release several hormones which regulate the functioning of different parts of the body. Growth hormone, PRL, TSH, ACTH, LH, FSH, MSH, oxytocin and vasopressin are the hormones released by the pituitary gland. Read More >>>

ENDOCRINE GLANDS AND HORMONES

Endocrine glands are ductless glands and their secretions are known as Hormones. They are chemical messengers which are secreted in trace amounts and affects the target organ of the body. Read More >>>

PHOTOCHEMICAL AND BIOSYNTHETIC PHASES OF PHOTOSYNTHESIS

The entire process of photosynthesis takes place in chloroplast.Photosynthesis comprises of two phases; Photochemical phase or light reaction or light dependent process and second phase is the biosynthetic phase or dark reaction of photosynthesis. Read More >>>

CYCLIC AND NON- CYCLIC PHOTOPHOSPHORYLATION

In plants photosynthesis results in the production of ATP and NADPH by two step process is called non- cyclic photophosphorylation.The photophosphorylation occuring in a cyclic electgron transport called cyclic photophosphorylation. Read More >>>

C3 AND C4 PATHWAY

Melvin Calvin proposed the C3 pathway and showed that the pathway operated in a cyclic manner; RuBP was regenerated. C4 pathway was worked out by Hatch and Slack where Kranz anatomy is found. Read More >>>

PHOTORESPIRATION

Photorespiration is a biochemical process in plants especially under conditions of water stress and oxygen. RuBisCo is the most abundant enzyme which fixes CO2 during the Calvin cycle. Read More >>>

CHEMIOSMOTIC HYPOTHESIS

Chemiosmotic hypothesis was proposed by Peter Mitchell in 1961 to describe ATP synthesis by way of a proton electro-chemical coupling. Read More >>>

PIGMENTS INVOLVED IN PHOTOSYNTHESIS

Pigments are molecule that absorb certain wave length of light and reflect all others,. There are two types of pigments; main pigments and accessory pigments. Read More >>>
