Answer:
Explanation:
Photosynthesis and cellular respiration (aerobic) are both metabolic processes that occur in specialized organnelles of living cells. These two processes are so unique to one another in the sense that one uses the product of the other as a reactant and vice versa.
Photosynthesis is an anabolic reaction that occurs in the Chloroplast of autotrophs in which captured energy from sun is used to synthesize organic food (glucose) by combining carbondioxide (CO2) and water. Oxygen is released in this photosynthetic process.
6CO2 + 6H20 --------> C6H12O6 + 6O2
Aerobic cellular respiration, on the other hand, is a catabolic process undergone by every aerobic living cell (in the mitochondria) in which glucose is broken down in the presence of oxygen to produce ATP (energy) releasing CO2 and water (H2O) in the process.
C6H12O6 + 6O2 ------> 6C02 + 6H2O
One spectacular difference is that photosynthesis uses solar energy (from sun) while aerobic cellular respiration uses chemical energy to power the process.
True.
The earth is made of several subsystems or spheres that interact to form a complex and continuously changing (dynamic) state that is termed as the earth system.
Even though the earth system is a closed system, it self regulates through the subsystems such as the water cycle and carbon cycle.
The earth system is characterized by numerous overlapping cycles in which matter is recycled over and over again. Cycles involve multiple spheres and systems interactions. Humans impact and are impacted by the cycles in various ways.
Answer:
Tight junctions are specialized regions of the plasma membrane that mediate separation of the apical and basolateral membranes.
Explanation:
Transcellular Transport is the pathway in intestinal epithelial cells where particles move from one cell to another depending on the physicochemical properties of the particles passing both the the apical membrane and basolateral membrane. Tight junctions create a paracellular barrier in epithelial and endothelial cells protecting them from the external environment
Answer:
The regulation of inflammatory responses at the site of infection is an example of paracrine signaling.
Explanation:
Paracrine signaling is a type of signaling where the cell communicates with their neighbor cells through the secretion of the signaling molecules. These signals move by the process of diffusion through the extracellular matrix.
Paracrine signaling helps in many biological activities in the body such as blood clotting, tissue repair, and reaction against allergens. Transfer of signals across a junction between two nerve cells is an example of practice signaling.
