In which cell structure does MOST of the process of cellular respiration take place?

1 answer:

6 0

Mitochondria are rod-shaped organelles are basically considered the power producers of the cell, it converts oxygen and nutrients into adenosine triphosphate or ATP, which is the chemical energy,also known as "currency" of the cell which powers the metabolic actions of the cell. This process is called aerobic respiration and it is the reason animals breathe oxygen. Cellular repiration happens in the mitochodrion. The 3 phases of cellular respiration are Krebs Cycle, Electron Transport and Glycolysis (Fermentation). Glycolysis takes place in the cytoplasm while the Krebs cycle and electron transport take place in the mitochondria.

A piece of hot metal is put into an equal mass of water. The water temperature rises 5o and the metal’s temperature drops 10o. W

Mice21 [21]

Answer:

The answer to your question is Cm = 2.093 J/kg°C

Explanation:

Data

mass metal = mass of water

Δ water = 5°

Δ metal = 10°

Cm = ?

Cw = 4.186 J/Kg°C

Formula

for metal for water

mCmΔTm = mCwΔTw

Cancel mass of metal

Cm ΔTm = CwΔTw

solve for Cm

Cm = (CwΔTw) / ΔTm

Substitution

Cm = (4.186 x 5) / 10

Simplification

Cm = 20.93 / 10

Result

Cm = 2.093 J/kg°C

The vapor pressure of liquid pentane, C5H12, is 40.0 mm Hg at 244 K. A sample of C5H12 is placed in a closed, evacuated containe

Rudik [331]

Answer:

b. The pressure in the container will be 100mm Hg.

d. Some of vapor initially present will condense.

Explanation:

The vapor pressure of liquid Pantene rises when there is container where evacuation of water molecules is restricted. The pressure inside the container rises to 100 mm Hg and then liquid molecules start condensing. These molecule form vapors.

At what point will potential energy be the highest? The object has a mass of 5 kg

Sloan [31]

Explanation:

Given that,

The mass of the object, m = 5 kg

We need to find the maximum potential energy. When the height of the object is maximum it will have the maximum potential energy.

The attached figure shows that the maximum height is 25 m. The formula for the potential energy is given by :

$P=mgh\\\\P=5\times 9.8\times 25\\\\P=1225\ J$

So, when the height is 25 m, the object will have the highest potential energy.

The compound KOH is ________. insoluble, because all compounds containing K are insoluble insoluble, because all compounds conta

Serhud [2]

Answer:

soluble because all compounds containing K are soluble

Explanation:

Most metal hydroxides are insoluble. However, alkali metal hydroxides (such as KOH and NaOH) are very soluble.

In the case of KOH, the K cation is attracted to the electronegative oxygen on water. The OH anion is capable of hydrogen bonding to the water. (Notice how OH⁻ is simply the deprotonated form of water.)
