When people run quickly, they can sweat profusely. their muscles undergo movement, and the loss of energy takes place. based on this description, in which two ways is energy conserved when people run?

⭕heat energy is released from the body to the surroundings.

⭕heat energy is taken from the surroundings to the body.

⭕chemical energy is converted to mechanical energy that’s used for muscle movements.

⭕radiant energy is converted to mechanical energy that’s used for muscle movements.

⭕heat energy is converted to mechanical energy that’s used for muscle movements.

what is the primary biomolecule that cells use for energy?

a. atp
b. glucose
c. nadh
d. nadph
e. oxygen

which important biochemical process receives a supply of nad+ ions from the fermentation process during anaerobic respiration?

a. calvin cycle
b. electron transport system
c. glycolysis
d. krebs cycle
e. proton pump mechanism

Heat energy is released from the body to the surrounding environment and Chemical energy is converted into mechanical energy that is used for the  movements of muscles and locomotion are the two ways in which our body conserved energy. Heat energy is produced during chemical reaction which increases the temperature of body so its release from the body is beneficial.

ATP is the primary biomolecule that is used by the cells for energy when the glucose is broken down in the mitochondria which also known as the power house of the cell.

Glycolysis is the process which receives a supply of NAD+ ions from the process of fermentation that occurs during anaerobic respiration.

So, first question:

When we run, we sweat, which means we're getting hotter and hotter and our bodies need to cool down, which they do through transpiration (sweating). If we need to cool down, we need to release the heat that is in our bodies.

To run, we also need to move our muscles, which requires a specific type of energy, called mechanical or kinetic energy, which is the "energy of movement". In our bodies, we don't store that type of energy though, so we have to convert chemical energy to mechanical energy.

Answers: First option and third option.

Second question:

We know that to move we need energy, and that an amazing source of energy is sugar. In this case, the biomolecule mainly used by cells to obtain energy, is glucose, which is a type of sugar.

B.

Third question:

NAD+ stands for Nicotinamide adenine dinucleotide +, an it has many functions, such as an oxidiser. In this case, in fermentation, it's related to glycolysis.

Glycolysis is a process of energy transformation used by cells, where they convert sugars to biochemical energy. The function of NAD in this case, is "housing" electrons for the process to function normally. Note that during the process, when NAD accepts electrons, it gains 1 proton which converts it to NADH.
