How does the equation for cellular respiration compared with the equation for photosynthesis?
nignag [31]
In plants, photosynthesis, occurring in chloroplasts, is an anabolic (bond-building) process whereby CO2 and H2O combine with the use of light (photon) energy. This yields O2 and sugar (i.e. glucose). This occurs in 2 phases: light-dependent and dark (Calvin cycle) reactions, which both continually recycle ADP/ATP and NADP/NADPH.
The catabolic (bond-breaking) process in plants is cellular respiration, in which glucose is broken down with O2 by glycolysis (cytoplasm only) and mitochondrial reactions (Krebs cycle and E.T.C.) to yield CO2 and H2O. These reactions recycle ADP/ATP and NAD/NADH. The CO2 and water produced by cellular respiration feed into the photosynthetic processes, and in turn, the O2 and glucose resulting from photosynthesis supply the respiratory reactions.

vegetarian diet has many health benefits. However, some issues need to be considered before removing animal products from the di
pychu [463]

Answer:

<h2>Vegetarians, especially vegans, need to consume adequate amounts of the essential amino acids by choosing complementary proteins and eating plant sources of complete protein like soy and quinoa.</h2>

Explanation:

Vegetarian diet does not contain all the essential amino acids. Amino acids are of two types, essential and non- essential amino acids. The essential amino acids are not synthesized by our body so we must have to take these essential amino acids through food. So vegetarians, especially vegans, need to consume adequate amounts of the essential amino acids by choosing complementary proteins and eating plant sources of complete protein like soy and quinoa.

Shana is a competitive athlete who weighs 135 lb. she would like to plan a nutritionally adequate diet that provides enough carb
prisoha [69]
The correct answer is d.

Carbohydrates are a very important part of an athlete's diet, since they provide the necessary energy for competition and endurance, but also help in the process of muscle gain.

The amount of carbohydrates that Shana should consume depend heavily on the intensity of her exercise activities. For a moderate level of exercise, which equals to 1 hour of exercise daily, a person should consume 5-7 g/kg of body weight. For a high level of exercise (1-3 hours of daily exercise), a person should consume 6-10 g/kg.

Guessing that Shana will perform a high level of exercise and based on her weight (135 lb or 61.2 kg), Shana should consume 366 to 610 g of carbohydrates daily.
