Answer:
The radiant energy of the sun is used by chlorophyll as an energy source to excite photosystems I and II, which are located in the membrane of the thylakoid.
Explanation:
When the light energy is converted into chemistry inside the photosystem, electrons are released and travel from photosystem II to photosystem I, through a protein complex; plastoquinone, cytochrome B, and plastocyanin.
When light hits, enzymes with REDOX power are activated while in photosystem I, one of the electrons converts NADP to NADPH, capturing protons from the stroma. Finally the NADPH and the ATP generated by the ATP synthetase of the thylakoid membrane, are products of the light stage of photosynthesis
It can be performed on any lobe in the body eg thyroid lobe, heart lobe
Answer:
ACTH
Explanation:
Corticotrophs from anterior pituitary gland secretes adrenocorticotropic hormone under stress conditions. ACTH stimulates the cortex of the adrenal gland to secrete glucocorticoids. Cortisol is the main glucocorticoid secreted by the adrenal cortex. This hormone triggers the break down of fats and proteins as well as stimulate gluconeogenesis. All these physiological responses prepare the body to combat stress or emergency conditions.
Answer:
<em>Listeria</em>
Explanation:
<em>Listeria</em> causes invasive syndromes such as meningitis, sepsis, and stillbirth in pregnant or immunosuppressed people. It is an intracellular pathogen and affects the persons with deficient cell-mediated immunity. Bacteria from this genus are part of the normal gastrointestinal microbiota in healthy individuals. However, in immunosuppressed individuals, the bacterium uses proteins such as internalin and phospholipase C for invasion, intracellular multiplication, and cell-to-cell spread.
Pregnant women are at the increased risk of infection due to both systemic and local immunological changes that mostly occur during pregnancy. For example, local immunosuppression at the maternal-fetal interface of the placenta may support the intrauterine infection.
