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

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.

In the absence of oxygen, glucose is broken down to create carbon dioxide during cellular respiration.
Is the above statement true or false?

• The respiration in the absence of oxygen is known as anaerobic respiration.
• Glucose is broken down into alcohol and carbon dioxide in the absence of oxygen.

Which of the following consumers eat plants?

• Cow , horse and rabbit are herbivores because they eat grass or components of plants.

When a molecule is broken down during respiration in plants, a tiny fraction of chemical energy gets converted into heat.
Is the above statement true or false?

• During respiration a glucose molecule is broken down into water and carbon dioxide.
• Also during the process a small amount of chemical energy is transformed into heat.

Sun's energy is turned into chemical energy in plants through which process?

• Producers make their own food for themselves and consumers by the process of photosynthesis.

From where does the majority of energy come?

• As sunlight is used in photosynthesis by producers, sun is the biggest source of energy.
• Consumers also depend on producers for their food and energy.
