BIO SEMESTER REVIEW (PART 2) - Cell Energy, DNA

Front

What is the light reaction in photosynthesis?

Back

The light reaction converts light energy into chemical energy in the form of ATP and NADPH.

Front

What percentage of each new DNA strand is made up of the old strand during DNA replication?

Back

Half of each new DNA strand is the old DNA.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light reactions and the Calvin cycle.

Front

What is the main source of energy for all life on Earth?

Back

The main source of energy for all life comes from the sun.

Front

Which base does Guanine bond with in DNA?

Back

Guanine bonds with Cytosine.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the set of chemical reactions that take place in chloroplasts during photosynthesis, where carbon dioxide is converted into glucose.

Front

What is ATP and its role in cellular processes?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

What is the function of NADPH in photosynthesis?

Back

NADPH is used as a reducing agent in the Calvin cycle to help convert carbon dioxide into glucose.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen, while anaerobic respiration occurs without oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the pigment that absorbs light energy, primarily from the sun, to drive the photosynthesis process.
