Answer:
Cross bridge in a sarcomere of a fast fiber produce higher amounts of force as compared to a cross bridge in a sarcomere of a slow fiber
Explanation:
When a muscle contracts, a cross bridge is formed between actin and myosin. The sarcomere shortens when a muscle contracts by reforming cross bridge. In general a muscle fiber is of three types – a) slow, b) Fast and c) intermediate.
The sarcomere of fast fiber generates high force but for a short period of time. On the other hand, sarcomere of slow fiber generate lower amounts of force but this force lasts for a longer period of time. Due to this difference, fast fibers are the predominant fibers in the body
Answer:
Water Use.
Explanation:
The other answers do not apply here
Answer: a.b.c-true.
d-false.
a. Some of the energy stored in glucose will eventually be transformed into heat.
This is through the process of Glycolysis (and Krebs's cycle )where the Carbon atoms in the glucose(substrate level phosphorylation) undergo metabolism with the liberation of ATPs as heat during metabolisms. The glucose serves as the substrate for the generation of heat.However,largest amount of ATP's is expended as heat during oxidative phosphorylation,due to the glucose used as substrate in preceding stages of glycolysis and Kreb Cycle.
b. Carbon atoms from glucose could be exhaled by the person as carbon dioxide.
Yes, this is through glycoylsis and kreb's Cycle where CO2 is given off as during metabolisms as one compound change from one form to another.E.g from Citric acid(6C) to Succinate(5C),some Carbon atoms are lost as C02. Like during glycolysis.
C. Carbon atoms from glucose could later be found in a plant cell.Yes this is because the CO2 expired by human could be trapped by green plants and react with water in the presence of sunlight trapped by chlorophyll to form carbohydrate in plants.This is photosynthesis.
Explanation:
Carbon can't not be converted to oxygen,big FALSE.
An advantage of sexual reproduction is that a genetic disorder in a parent might not affect the offspring
I think its 2, but I'm not sure. I have the same question on my homework, but I don't know. I'm 82% sure its A.
Hope this helps:)
