Answer:
SA Node
Inter-nodal Pathways
AV Node
AV Bundle
Bundle Branches
Purkinje Fibers
The SA nodes functions first for setting pace for the heart, then the inter-nodal pathway make link b/w SA and AV node. AV node is site of delay when contraction of atria occurs. AV bundle is the mean of electrical link b/w atria and ventricle. The conveying of impulse to the inter-ventricular septum occurs through bundle branches, while conveying of impulse throughout and along the walls of ventricle occurs through Purkinje fibers.
‘Family planning’ is a broad term that includes any measures taken to responsibly prevent pregnancy (birth control, contraception, planning, abortions, permanent infertility procedures, etc.).
Birth control, however, is specifically designed to intervene in a woman’s natural hormones to drastically reduce the possibility of pregnancy (much like contraception)
Answer:
Respiration links up the simple sugar, <u><em>glucose</em></u><em>,</em> with the gas <u><em>oxygen .</em></u>
Explanation:
In the process of respiration, oxygen is used to breakdown glucose. Water and carbon dioxide are produced due as a result of this reaction. A huge amount of energy, in the form of ATP is also released during this process. ATP is used by almost every cell of the body to carry out normal cellular functions. Energy is mainly stored in the linkage between the second and third phosphate of an ATP molecule.
Answer:
Photosystem I (PS-I )and photosystem II (PS-II ) are two multi-protein complexes. These complexes contain the pigments used to absorb, harvest and catalyze the photons and light energy in the photosynthetic reactions. The main purpose of photosynthesis reactions to produce high chemical energy compounds.
Photosystem I and II are different from each other because of their absorbing wavelength of light. PS-I absorbs the longer wavelength of light than PS-II.
PS-I plays the major role in the production of high energy carriers ATP and NADPH using light energy (700 nm).
PS-II plays its function in the hydrolysis of water and ATP synthesis using light energy (680 nm).
The answer is Cell Membranes.
