Why is pyruvate imported from the cytoplasm into the mitochondrial matrix?

Biology
1 answer:
grin007 [14]3 years ago
4 0

Answer:

So that oxidation of pyruvate can take place in mitochondria.

Explanation:

Pyruvates is produced in the glycolysis process which occurs in the cytoplasm. So pyruvate is produced in the cytoplasm of the cell. Pyruvate is produced by partial oxidation of glucose and to be fully oxidized it has to enter in the mitochondria.

So after entering the mitochondria the pyruvate first converts into acetyl CoA than this acetyl CoA enters in the citric acid cycle and fully oxidized into CO2. This oxidation generated NADP and FADH2 which provide reducing power during oxidative phosphorylation.

NEED HELP ASAP!!!!<br> Name one advantage of light microscopes<br> over electron microscopes.
Maslowich

Answer:

The biggest advantage is that they have a higher resolution and are therefore also able of a higher magnification (up to 2 million times). Light microscopes can show a useful magnification only up to 1000-2000 times. This is a physical limit imposed by the wavelength of the light.

7. What is the kinetic energy of a 3-kilogram ball that is rolling at 2 meters per second?
nydimaria [60]
Kinetic energy = 0.5*M*V^2 

 Q7-
 
0.5*3*(2^2)= 6J

Q8a- 

0.5*2*(2^2)= 4J
0.5*4*(3^2)=18J 
the second ball has more kinetic energy.

Q8b-

at the max height, all the kinetic energy is converted to potential energy, 

gravitational potential energy is = M*g*h

that theory would apply if you wanted to work out the maximum height achieved if the balls were thrown upward by rearranging. But, we are simply working out which ball will have more potential energy so:

First ball:
2kg*9.81(g)*10m = 196.2J

Second ball
4kg*9.81*10m= 392.4J

The second ball has more potential energy

Please help me!! Describe the effect of surface area and pores on cells.
ivanzaharov [21]

Explanation:

Surface area and pores play important roles in the cell.

Pores are the tiny holes on the surfaces of a body. They help to facilitate movement of materials in and out of the cell.

The surface area is the amount of space the surface of a cell occupies.

  • Pores in a cell needs to be in proper shape in order to facilitate movement of materials.
  • When the pores in a cell are too large, too much materials are bound to leave the cell. Tiny pores makes it difficult for the cells to have enough materials to function properly well.
  • The surface area of a cell allows for the diffusion of materials in and out of cell.
  • The larger the surface area of a cell, the more and better reactions takes place because they will receive important life sustaining resources.
