ATP and NADPH are generated during the light reactions. In which set of metabolic reactions are they actually used? a· light reactions b. aerobic respiration c. Calvin cycle d. transition reaction e. CAM metabolism 2. What kind of cell undergoes meiosis in most fungi? a. somatic cell C. germ cell d. gamete e. haploid cell 3. The portion of the electromagnetic spectrum that ranges from approximately 380 nm to about 750 nm is known as a.

In order to divide, most mammalian cells have to be attached to a substratum through the extracellular matrix. T known as a. transformation b. anchorage dependence c. interkinesis d. independent assortment e. density-dependent inhibition 7. In some cases, enzymes cannot catalyze a substrate because an inhibitor has bound to the active site. Thi known as: a. noncompetitive inhibition b. feedback inhibition c. allosteric regulation d. competitive inhibition e. substrate-level phosphorylation

Explanation / Answer

1)c) Calvin cycle

ATP is used as chemical energy

NADPH is used as reducing power

2)b) zygote

Meoisis results in haploid cells

These haploid cells undergo mitosis to form organism

3)c)visible light

X ray-10pm to 10 nm

Infrared-750nm to 1mm

Radio waves-100mm to 10,000km

UV rays- 10nm to 380nm

4)a) allosteric

It is the regulation of activity of enzyme or protein

It causes the change in the shape of the active site and prevents binding of substrate
