Answer:
The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In many ways, respiration is the opposite of photosynthesis. In the natural environment, plants produce t
Answer:
Bulk flow
Explanation:
Generally when there is mass movements of molecules of the fluids from a high pressure gradients to low pressure gradients; that is down the concentration gradients, the process is called Bulk flow. In relation to cells, it is the exchange of material between cells through the pores of the adjoining cells. In xylem , water and minerals flow from high pressure roots to the leaves, and phloem transport food substances from the leaves the sources at high pressure to other parts of the plants.
The capillary transport mechanisms involves the movements of fluids, ions across the fenestration of the capillaries due to the hydostatic pressure of the fluid from the high pressure to the low pressure cellular environments.This is common in the glomerulus of the kidney, intestine, and some endocrine glands.
The single wall endothelial lining of capillaries forms continuous wall which allows passage of ions and fluids while restricting movements of large molecules. Generally the high pressure from the hydrostatic pressure forces these materials across the walls.
Simple diffusion which follows concentration gradient across membranes ensures distribution of substances across the walls for fast uptake by the cells.
The movement of Macromolecules across capillary wall is called vesicular transport.
Thus Bulk flow is odd.
A) Thylakoid
B) Lumen
C) Granum
D) Stroma
Answer:
Hydrogen and electrons
Explanation:
Nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD) serve as reducing power during energy transfers. One NAD+ accepts one hydrogen ions and two electrons and becomes reduced into NADH. Likewise, FAD accepts two hydrogen ions and two electrons and is reduced into FADH2. Oxidation of NADH and FADH2 into NAD+ and FAD respectively releases both hydrogen ions and electrons.
For example, some of the energy of glucose released during glycolysis and Kreb's cycle is temporarily stored in the form of NADH and FADH2. Oxidation of NADH and FADH2 via electron transfer chain of mitochondria releases both electrons and hydrogen ions (protons). The protons are pumped across the inner mitochondrial membrane to generate the proton concentration gradient.
Answer: 400 Micro-grams
Explanation:
The institute of the medicine, suggest all the women who are pregnant should consume atleast 400 micro-gram per day. In year 1998, this institute take the responsibility to recommend all the pregnant women about their diet plans.
They recommended to take 40 micro gram per day of the synthetic folic from the supplements and fortified food. The folic acid is the type of synthetic vitamin B. The women should consume the food from, the varied diets as it helps to prevent the brain of the baby and also from birth defects.
