Yucca is a genus of perennial shrubs and trees in the family Asparagaceae, subfamily Agavoideae. [2] Its 40–50 species are notable for their rosettes of evergreen , tough, sword-shaped leaves and large terminal panicles of white or whitish flowers .
Macronutrients are defined as a class of chemical compounds which humans consume in relatively large quantities compared to vitamins and minerals which provide humans with energy. Fat has a food energy content of 38 kilojoules per gram (9 kilocalories per gram) proteins and carbohydrates 17 kJ/g (4 kcal/g). [2]
The cassava plant gives the third-highest yield of carbohydrates per cultivated area among crop plants, after sugarcane and sugar beets. [68] Cassava plays a particularly important role in agriculture in developing countries, especially in sub-Saharan Africa , because it does well on poor soils and with low rainfall, and because it is a ...
In most organisms, excess carbohydrates are regularly catabolised to form acetyl-CoA, which is a feed stock for the fatty acid synthesis pathway; fatty acids, triglycerides, and other lipids are commonly used for long-term energy storage. The hydrophobic character of lipids makes them a much more compact form of energy storage than hydrophilic ...
Yucca elata is a perennial plant, with common names that include soaptree, soaptree yucca, soapweed, and palmella. [3] [4] It is native to southwestern North America, in the Sonoran Desert and Chihuahuan Desert in the United States (western Texas, New Mexico, Arizona), southern Nevada, southwestern Utah, and northern Mexico (Chihuahua, Coahuila, Sonora, Nuevo León).
The Joshua tree is called "hunuvat chiy'a" or "humwichawa" by the indigenous Cahuilla. [11] It is also called izote de desierto (Spanish, "desert dagger"). [12] It was first formally described in the botanical literature as Yucca brevifolia by George Engelmann in 1871 as part of the Geological Exploration of the 100th meridian (or "Wheeler Survey").
Yucca aloifolia [4] is the type species for the genus Yucca. Common names include aloe yucca , [ 5 ] dagger plant , [ 6 ] and Spanish bayonet . It grows in sandy soils, especially on sand dunes along the coast.
The respiratory quotient value indicates which macronutrients are being metabolized, as different energy pathways are used for fats, carbohydrates, and proteins. [1] If metabolism consists solely of lipids, the respiratory quotient is approximately 0.7, for proteins it is approximately 0.8, and for carbohydrates it is 1.0.
