a glucose
b deoxyribose sugar
c adenine
d ribose sugar
e phosphates
f guanine

1. atp releases energy when a bond is broken between which of the following?

a the second and third phosphate groups
b adenine and ribose
c adenine and a phosphate group
d ribose and a phosphate group

1. why do cells tend to have more adp molecules than atp molecules?

a adp stores more energy.
b atp is used only by plant cells.
c adp is a smaller molecule than atp, so more adp molecules can fit into a cell.
d atp does not store long - term energy.

1. which of the following statements are true about atp? select all that are true.

a when atp releases energy, adp is formed.
b atp provides energy for cells to function.
c used atp is discarded by the cell as waste.
d a single molecule of atp stores more chemical energy than glucose.
e atp stores chemical potential energy in its phosphate bonds.

a the krebs cycle
b the calvin cycle
c electron transport
d glycolysis
e photolysis
f carbon fixation

1. aerobic respiration requires which of the following compounds?

a carbon dioxide
b oxygen
c chlorophyll
d water

1. which statement below best describes the main purpose of cellular respiration in cells?

a to obtain energy to use in other processes
b to form glucose and store energy in its chemical bonds
c to produce lactic acid in animals or to produce alcohol in plants
d to create carbon dioxide and water

1. cells use atp energy to move materials across cell membranes. which process(es) would you expect to use atp to release energy for cellular work? select all that apply.

a facilitated diffusion
b osmosis
c nerve transmission
d simple diffusion
e exocytosis
f muscle contraction

Explanation:

Question 1

To determine the components of ADP and ATP, recall their structure. ATP (adenosine triphosphate) and ADP (adenosine diphosphate) consist of adenine, ribose sugar, and phosphates (ATP has three, ADP has two). Glucose is a carbohydrate, deoxyribose is in DNA, guanine is a nucleotide base not in ADP/ATP. So the correct components are adenine (C), ribose sugar (D), and phosphates (E).

ATP's structure has three phosphate groups. Energy is released when the bond between the second and third phosphate groups is broken, forming ADP. The bond between adenine - ribose or ribose - phosphate is not the energy - releasing bond here.

ATP is used for immediate energy needs and is quickly converted to ADP after energy release. ADP can be recycled back to ATP. ADP does not store more energy, ATP is used by all cells, and size is not the reason for more ADP. ATP is for short - term energy, so cells have more ADP as ATP is used and regenerated, and ATP doesn't store long - term energy.

Answer:

C. adenine, D. ribose sugar, E. phosphates
