BioMed Activity 3.2.6 In Search of Energy

products of cellular respiration

6CO2 + 6H2O + ATP (carbon dioxide, water, and ATP)

what are the products for a hydrolysis reaction

ADP + Pi + energy

It is one of the most efficiently used compounds in nature.

ATP

______ is to cells what gasoline is to your car.

ATP

provides the usable energy needed to carry out all body processes.

ATP

what are the reactants for a hydrolysis reaction

ATP + H2O

what is the equation for the breakdown of ATP

ATP + H2O --> ADP + Pi + energy

what is ADP

Adenosine Diphosphate

where is energy located in a molecule of ATP

Bond between the 2nd and 3rd phosphate group.

reactants of cellular respiration

C6H12O6 + 6O2 (Glucose and Oxygen)

what is the equation for generating ATP

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

what happens to CO2 produced by cellular respiration

CO2 = carbon dioxide is released and exits the body when we breathe out.

Identify what foods are considered good energy sources.

Carbohydrates: pasta, rice, bread etc... Glucose is needed to produce ATP, so food sources that contain carbohydrates are necessary.

where does glucose come from for cellular respiration

Glucose, which we get from our food

Name the process human cells use to generate more ATP. Where in the cell does this process occur?

Glycolysis → cytoplasm Aerobic cellular respiration → Mitochondria

What is hydrolysis?

Hydrolysis → "Hydro" = water; "Lysis" = Breakdown; literally means to break down with water. Used to separate the 3rd phosphate group from a molecule of ATP to create ADP.

How is ADP generated?

It is created when the 3rd phosphate group breaks off during the hydrolysis reaction.

which types of cells in the body require the most ATP

Muscle cells (called myocytes) (includes cardiac muscle cells), neurons, and sperm

Name 3 specific body processes that require energy.

Muscle contraction and relaxation Active transport of molecules across membranes; example: Nerve conduction → sodium-potassium pump in neurons.

where does oxygen come from for cellular respiration

O2 = oxygen, is taken in when we breath

what are the 3 components of an ATP molecule

Sugar = Ribose Base = Adenine 3 phosphate groups

what reaction generates ATP and where does it take place

cellular respiration in the mitochondria of the cell

what is ATP used for in the human body?

energy and allows us to do work

what provides us with ATP

food

what type of reaction breaks down ATP

hydrolysis

what is ATO a type of

nucleic acid
