Chapter 8 Biology

What would most likely happen to a healthy, green leaf that was covered with aluminum foil?

• the leaf would remain green because it would continue to perform photosynthesis

• the leaf would fall off due to lack of oxygen

• the leaf would lose its green color due to the breakdown of chlorophyll in the leaf

• the rest of the plant would die due to lack of nutrients

One way cells use the energy provided by ATP is to

• carry out active transport

• add an additional phosphate group

• remove two phosphate groups

• carry out osmosis in the cell

Why are mushrooms considered heterotrophs?

• Mushrooms make their own food

• mushrooms feed through photosynthesis

• mushrooms trap & eat small flying insects

• mushrooms eat by absorbing decomposing nutrients from organisms

The photosystems contain pigments that absorb light and pass the energy on to

• NADPH

• ATP

• ADP

• electrons

The electrons carried by NADPH are similar to a hot potato in that both

• have a lot of energy & require a carrier to be transported

• are used in cells & require a carrier to be transported

• have a lot of energy & glow red-hot

• require a carier to remove excess energy

What is the difference between ATP and ADP?

• ATP powers movement, while ADP does not

• ATP has 3 phosphate; ADP has two

• ATP contains adenine & ribose, while ADP does not

• ATP has less energy than ADP

Organisms that make their own food are called

• heterotrophs

• autotrophs

• homotrophs

• polytrophs

Energy is released upon the conversion of

• AMP to ADP

• ADP to ATP

• ATP to ADP

• ATP to AZP
