Biology - Photosynthesis: A Closer Look

The chemical energy stored in ATP during photosynthesis is released during the dark phase to:

produce a carbohydrate from CO2

a food made up of carbon, hydrogen, oxygen, nitrogen

protein

the putting together of protein molecules from amino acids

protein synthesis

Enzymes are:

proteins

Match the associations with the "light" and "dark" phases of photosynthesis- solar energy: CO2 intake: release of energy: storage of energy: release of O2: release of water: ATP: forms carbohydrates:

!. Light 2. Dark 3. Dark 4. Light 5. Light 6. Dark 7. Light 8. Dark

the high energy chemical compound that provides energy

ATP

For maximum photosynthesis, increased light intensity has greater effect than increased leaf surface area.

False

Proteins are the building blocks of amino acids.

False

Proteins of one plant are like proteins of other plants, but animal proteins are unlike each other and plant proteins.

False

Protoplasm consists of numerous combinations of 22 proteins.

False

Ribosomes are only found in plant cells.

False

A green house may be used to control temperature and carbon dioxide.

True

A tiny body with plant cells, the chloroplast, is the power generator for life on earth.

True

Animals and humans cannot live without protein in their diet.

True

Carbon dioxide levels above normal will increase plant growth of other factors are adequate.

True

Enzymes are an example of proteins.

True

Some of the most complex organic molecules are those of proteins.

True

the building blocks of proteins

amino acid

The building blocks of proteins are _____________.

amino acids

Since carbon as an atmospheric gas is locked into a food molecule, it is termed carbon dioxide fixation.

dark reaction

provides energy storage and structure for life

fat

Each protein molecule is made of at least __________ amino acid units.

fifty

Proteins may be identified separately from fats and carbohydrates by the presence of certain elements. Choose the elements that qualify.

iron sulfur phosphorous zinc nitrogen

Hill is known for working out reactions taking place during the ________________ of photosynthesis.

light reaction

The twenty two amino acids are capable of producing ______________.

millions of different proteins

All proteins contain ________________, in addition to carbon, hydrogen, and oxygen.

nitrogen

essential to aerobic respiration

oxygen

Proteins are made by:

ribosomes in plants and animals

Van Niel's theory, later shown to be correct, claimed that the oxygen produced by photosynthesis comes from the ________________________.

splitting of the water molecule

The oxygen which is released into the air by a plant originated from:

splitting of water molecules

the tiny pores or leaf openings appearing between guard cells

stomate

Photosynthesis continues to increase with temperature:

true within limits
