Explain the process of the electron transport chain. where do the molecules used in the process come from? what powers the proce
Advocard [28]
Process of Electron Transport Chain (ETC), is a series of transferring from electron donors to their acceptors.  It basically means a transfer from high energy molecule to a low-energy molecule.  This process of extracting energy by transfer is classified as a chemical reaction and we see it is the path taken of cellular respiration (NADH) and FADH2) and in photosynthesis, NADPH.  It starts with an electron, NADH and FADH2, when the electron donors release a proton gradient and it creates an imbalance.  Think of it as a see-saw with one heavy person on one end and a lighter one on the other end.  The protons actually attempt to defuse back across this see-saw of a membrane and it releases energy during the cross over which we call Chemiosmosis.

Please help!! Can you figure out the modern spreading rate of the Mid- Atlantic ridge? Use that line to figure out how many kilo
bija089 [108]

Answer:

R = 16mm/y  

Explanation:

Modern Spreading Rate (R) = distance the seafloor moved in km (d) / age in million years (t)

R = d/t  

To calculate it in millimeters per year we need to convert it:

<em>1 km = 1000 m  </em>

<em>1 m = 100 cm </em>

<em>1cm = 10mm </em>

<em>1 km = 1,000,000 mm   </em>

The problem states that in 150 million years, there is a distance of 2400 km.

if 1 km ------- 1,000,000 mm

2400 km-------X = 2400,000,000 mm

If 1 million years -------1,000,000 years

150 my----X = 150,000,000 years

R = d/t

R = 2400,000,000 mm/150,000,000 y.

R = 16mm/y

Glucose molecules provide energy to power the swimming motion of sperm. In this example, the sperm are changing
Mazyrski [523]

Answer:

From the energy stored in food substance( glucose) as Chemical energy to the energy of motion,which is Kinetic energy.

Explanation:

The energy is produced in the mitochondria which are packed in the flagellum of the  a sperm cells.Thus as the sperms move the these flagella flips  back and forth,Energy inform of ATPs are generated from the glucose(chemical energy) during cellular respiration in the mitochondria, this  energy is converted to  Kinetic energy for motility.

Specifically,ATP production for the sperm cells is initiated by  Glycolysis. This is because the environments where it swims to meet the ovum punctuates with in oxygen, besides,Glycolysis can occur with or without oxygen.

Sperm motility is very important to male fertility.
