Which of the following is the process where energy is extracted from glucose?

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

• As ATP provides readily releasable energy in the bond between the second and third phosphate groups, it loses third phosphate group to release energy.

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.
