Mr. Grimes Cellular Energy Study Guide

What is the definition of energy?

• ATP

• Matter

• The ability to do work

• Energy cannot be created or destroyed only transformed

what is metabolism?

• All processes an organism does

• all chemical reactions that occur within an organism

• processes that only occurs in cells

• chemical reactions that occur anywhere

Define Photosynthesis

• two-phase catabolic pathway in which the sun's light energy is converted to chemical energy for use by the cell

• one-phase anabolic pathway in which the sun's light energy is converted to chemical energy for use by the cell

• two-phase anabolic pathway in which the sun's light energy is converted to chemical energy for use by the cell

• one-phase catabolic pathway in which the sun's light energy is converted to chemical energy for use by the cell

what is ATP ( Adenosine Triphosphate)?

• energy-obtaining biological molecule

• drives activities of the cell when left intact

• drives activities of the cell when broken down

• energy-carrying biological molecule

Define Cellular Respiration

• catabolic pathway in which organic molecules are broken down to release energy for use by the cell

• anabolic pathway in which organic molecules are broken down to release energy for use by the cell

• catabolic pathway in which organic molecules are broken down to release energy for use by the animal

• anabolic pathway in which organic molecules are broken down to release energy for use by the animal

how many ADP turn into ATP in Glycosis and when?

• 2 ADPs turn into ATP after G3P

• 2 ADPs turn into ATP before G3P

• 4 ADPs turn into ATP before G3P

• 4 ADPs turn into ATP after G3P

What are the name(s) of the first phase of the process photosynthesis?

• PS I

• PS II

• Calvin cycle

• Krebs cycle

What is the last part of photosynthesis?

• Calvin cycles

• PS I

• electron transport system

• Krebs cycle

how many carbons from one glucose molecule enter one round of the Krebs cycle?

• 3 carbons

• 6 carbons

• 2 carbons

• 12 carbons

what are the steps of the Calvin cycle?

• step 3: some G3P molecules leave the cycle to be used for the production of glucose and other organic compounds

• step 2: energy stored in ATP and NADPH is transferred to the 3-PGA to form G3P

• step 1: carbon fixation

• step 4: Rubisco converts remaining G3P molecules into ribulose 1,5 biphosphate

• step 2: energy stored in ATP and NADPH is transferred to the 2-PGA to form G2P
