Bio chapter 9 review

Energy is defined as the ability to

• Communicate
• Reproduce
• Grow
• Do work

Which of the following is NOT a form of energy?

• Light
• Oxygen
• Heat
• Electricity

Which of the following is used by cells to store and release energy needed to power cellular processes?

• ATP
• RNA
• DNA
• NADP+

Heterotrophs get energy from______autotrophs_______their own energy

How can ATP store and release energy for the cell?

Plants use the green pigment chlorophyll to

• absorb sunlight
• store sunlight
• reflect sunlight
• change light to heat

High energy electrons are transported from chlorophyll to other molecules in the chloroplast by

• The thylakoid membrane
• Pigments like carotene
• Electron carriers like NADP+
• ATP synthase

Name 2 parts of the chloroplast where photosynthesis occurs.

The clusters of chlorophyll and proteins that absorb sunlight and generate high energy electrons in the chloroplast are called

• carrier proteins
• transport chains
• photosystems
• synthase proteins

In photosystem II as high energy electrons are passed to the electron transport chain the chlorophyll gains new electrons from

• oxygen atoms
• water molecules
• hydrogen atoms
• carbon dioxide
