Ch 5: Photosynthesis & Cellular Respiration
adenosine triphosphate, or ATP, is primarily used as _____________ in living organisms
A source of energy
During cellular respiration, energy is stored in the form of
ATP
The chloroplasts in the cell's of these organisms then transform the radiant energy into chemical potential energy stored in the bonds of
Highly condensed carbon compounds, such as carbohydrates
In the process of photosynthesis, plant cells take in water (H2O) and carbon dioxide (CO2) and release oxygen (O2). How is this different from what takes place in the process of aerobic respiration?
In aerobic respiration, cells take in O2 and produce CO2, H2O, and ATP
What type of macromolecule contains high-energy and is used for long-term energy storage?
Lipids
Which of a cell's organelles releases energy stored in food?
Mitochondria
cellular respiration occurs in the
Mitochondria
Organisms undergo many different processes in order to be able to store energy and utilize that energy. Through which of the following process is energy stored in the form of glucose?
Photosynthesis
What is TRUE about plants and cellular energy?
Plants can use light energy to produce food molecules or to obtain cellular energy from the bonds of these food molecules during cellular respiration
Photosynthesis is carried out by which of the following?
Plants, but not animals
What products in the process of photosynthesis?
Glucose and Oxygen
Which of the following are reactants in the process of cellular respiration?
Glucose and Oxygen
In the thylakoid are proteins that...
Help capture light from the sun during the process of photosynthesis
Which of the following are products in the process of cellular respiration?
Carbon dioxide and water
Which of the following are reactants in the process of photosynthesis?
Carbon dioxide and water
How do cells get energy to perform their necessary functions?
Cells get energy by taking in nutrients from food.
ATP molecules store cellular energy. When phosphate groups are removed and molecules of ADP are formed, energy is released. This energy can be used to perform...
Cellular work
In which organelle does photosynthesis take place?
Chloroplast
Which of the following organelles convert solar energy into glucose and oxygen?
Chloroplast
Which organelle in the plant cell makes glucose from sunlight?
Chloroplast
Through the process of hydrolysis, cells remove phosphate groups from molecules of ATP to form molecules of ADP. This hydrolytic reaction results in...
The formation of high energy bonds to store free energy
What is the function of stomata in plants?
To allow gas exchange between the environment and the inside of leaves
During photosynthesis, plants capture light energy from the Sun to break the bonds in reactants, such as carbon dioxide and water, and form carbon- containing molecules, such as glucose. The carbon-containing molecules can then be used.
To assemble larger molecules, such as DNA, proteins, and fats.
