What is the proton gradient used for in photosynthesis?
Dmitriy789 [7]
The energy of the electrons in NADPH are not sufficient for anabolic reactions such as CO2 fixation. These processes also require biochemical energy in the form of ATP. The process of photosynthetic electron transfer also generates a gradient of protons (H+) across the photosynthetic membrane (Figure: Proton Gradient).

Oxygen and CO2 are exchanged between capillaries and alveolus. Do capillaries contain deoxygenated blood while alveolous contain
dalvyx [7]
The aveolus is surrounded by capillaries. So capillaries carry deoxygenated blood to the alveolus where the oxygen from the alveolus diffuses into the blood in the capillaries. The deoxygenated blood is now oxygenated and is carried out of the lung via capillaries that then merge into the pulmonary vein.

In other words, alveolus does not have oxygenated blood it just puts oxygen into the deoxygenated blood hat this brought in.

Which type of cell is most likely to have the most mitochondria? muscle cells in the legs of a marathon runner nondividing cells
MatroZZZ [7]

Answer:

muscle cells in the legs of a marathon runner

Explanation:

Mitochondria are the powerhouse of cells and serve as a site for the aerobic stage of cellular respiration. Cellular respiration is complete oxidation of nutrients in the presence of oxygen to produce a large number of ATP molecules. Therefore, the cells that require more ATP molecules as an energy source would most likely have a greater number of mitochondria.

Muscle cells are responsible for body movement. Muscle cells in the legs of a runner would require a constant supply of ATP during running since muscle contraction requires ATP. To sustain the continuous muscle contraction during the marathon, the muscle cells in the legs of the runner would have most number of mitochondria.

What do climate change (see Concept 1.1 and Concept 3.2) and ocean acidification have in common?
leonid [27]

Answer:

They are caused by an increase in global temperatures

Explanation:

Global warming will cause a change in the weather patterns of a region – called climate change. A place could experience extreme weather such  as increased dryness or wetness.  This is mainly due to takeup of this heat by the oceans hence influencing global currents.

As the oceans become warmer, they are able to absorb more carbon dioxide from the atmosphere. This causes these water to have a higher acidity than normal because of the formation of carbonic acid.
