When a cell demands energy, ATP loses which phosphate group?

Which of the following is the process where chemical energy is transformed?

• During cellular respiration a tiny fraction of chemical energy is transformed into heat.

Adenosine molecules are bound to two phosphate groups to form ATP.
Is the above statement true or false?

• When adenosine have two phosphate groups it is called ADP (adenosine di phosphate).

Adenosine molecule is bound to how many phosphate groups?

• As it's name ATP has one adenosine and three phosphate groups.

Which of the following is the full form of ATP?

• ATP is also called as energy molecule having one adenosine molecule bound with three phosphate groups.

____ from cellular respiration is stored in the ATP link between the second and third phosphate group.

• ATP stands for adenosine tri phosphate.
• ATP provides readily releasable energy in bond between second and third phosphate groups.

When energy is drawn from the environment, it is known as ____ reaction.

• More energy is absorbed when bonds break than the energy released when bonds formed.

When energy is released into the environment, it is known as ____ reaction.

• When bonds are formed in product in a reaction, energy releases.

In the context of thermal reaction, how many thermal reactions are there?

• Thermolysis involves decomposition due to heat.
• Electrolysis involves decomposition due to electricity.

During energy releasing phase, how many NADH are made in total?

• During energy releasing phase of glycolysis there is formation of two ATP, 2 NADH and 2 pyruvate molecules.

During the energy releasing phase, how many ATP are made in total?

• There is formation of four ATP molecules during energy releasing phase.

During the energy requiring phase, the initial molecule of glucose is ____.

• There is rearrangement of first glucose molecule in energy requiring phase.

Which of the following is the phase of glycolysis?

• There are two phases of glycolysis: priming phase and pay off phase.

Glycolysis is divided into how many phases?

• There are two phases of glycolysis: 

1. Priming phase : it requires an input of 2 ATPs per glucose molecule.
2. Pay off phase: energy is released in the form of 4 ATPs, 2 per glyceraldehyde molecule.

Where does glycolysis occur?

• Glycolysis occurrs in cytoplasm and the product of the process is carbon molecules of pyruvate.
• The fate of pyruvate depends on the presence or absence of oxygen and mitochondria in the cells.

Which of the following is an energy-carrying molecule?

• Adenosine tri phosphate is known as energy molecule.
• Because it provides readily releasable energy in the bond between second and third phosphate groups.
