Answer:
the protons become concentrated in the thylakoid space
Answer:
Kerb cycle
<u>Explanation</u>:
The result from mitochondria is ATP, that acts as a currency of the energy in the cell. In the cytoplasm of mitochondria kerb cycle occurs. In this process it has several other process, once it uses acetate and water to give NADH from NAD+ and gives carbon dioxide as waste. The NADH formed is fed by oxidative phosphorylation or electron transport. The outcome of these processes is oxidation of nutrients to give chemical energy in ATP form.
Answer:
or 308 J
Explanation:
Work in physics is done when an object is moved due to an applied force. But you need to remember that work is only done if there is movement parallel to the direction of the force applied.
Work can be computed with the formula:
W=Fd
Where:
F = Force
d= distance
So your problem gives you:
F = 22 N (Newtos)
d = 14 m (meters)
All you need to do is plug in the values and multiply:
W = F x d
W = 22N x 14m
W = 308 N-m or 308 J (Joules)
Answer:
D. It keeps the temperature lower for sperm development
Explanation:
<u>Semineferous epithelium ,of the seminiferous tubules, of the testis is the site of sperm production (Spermatogenesis) , and highly sensitive to elevated and fluctuating body temperature of man. Elevated temperature affect the survival of spermatids , the spermatozaon, and therefore affects spermatogenesis</u>.
To avoid this the testis is located outside the body in the scrotal sack.This positioning aids shielding away of the elevated body temperature; thereby survival of spermatozoan.
The attachment in the scrotal sack is done by the cremasteric muscles of the scrotum. This muscle positions the testis in the best angle to reduce temperature conduct from the body.
It also help by contracting and relaxing, to adjusts the temperature of the testis depending on the environmental temperature.During cold showers,it constricts pulling it close to the abdomen, and after, relaxes returning it to normal position.
