8 1 energy and life
8-1: Energy and Life

  • Energy is the ability to do work

  • How do you get energy for you cells from the sun???

    • The answer involves 3 type of energy

SUN

ATP

GLUCOSE


ATP

  • ATP is the type of energy that cells can use

    • AdenosineTriphosphate (ATP)

Adenine base

3 phosphate groups

Ribose sugar

8 2 photosynthesis
8-2: Photosynthesis

  • In the presence of light, carbon dioxide and water is transformed into carbohydrate and oxygen.

    CO2 = carbon dioxide

    H2O = water

    C6H12O6 = glucose (carbohydrate)

    O2 = oxygen


Review chemical reactions
Review: Chemical Reactions

CO2 + H2O C6H12O6+ O2

What are the products? What are the reactants?


Photosynthesis
Photosynthesis

CO2 + H2O C6H12O6+ O2

  • This process occurs in the chloroplast and can occur because of the pigment chlorophyll.

    • A pigment is a protein molecule that can absorb light energy.

Analyzing data pg 213
Analyzing Data pg 213 necessary for photosynthesis EXCEPT


  • Factors Affecting Photosynthesis and Plant Adaptations necessary for photosynthesis EXCEPT

    • Water

      • Waxy cuticle on plants in dry climates reduces water loss

    • Temperature

      • Enzymes needed for photosynthesis work best 0-30oC

    • Intensity of Light

      • Plants work best in range of light intensity


Fall Colors necessary for photosynthesis EXCEPT

  • In the fall, because of changes in the length of daylight and changes in temperature, the leaves stop their food-making process. The chlorophyll breaks down, the green color disappears, and the yellow to orange colors become visible and give the leaves part of their fall splendor.

  • Calorie: amount of energy needed to raise the temperature of 1 gram of water 1 degree C


Ch 9 1 chemical pathways1
CH 9-1: Chemical Pathways necessary for photosynthesis EXCEPT

  • Food Energy the cell can use (ATP)

    • First step = glycolysis

    • Can then be completed with or without oxygen

      • Aerobic Respiration

      • Anaeronic Respiration

  • Mitochondria and Chloroplast both have shapes with high surface area to volume ratios to increase membrane space for reactions to occur

  • Both evolved from prokaryotes

    by the process of endosymbiosis

    • Both have DNA separate from

      nuclear DNA

      • In humans, all mDNA inherited from mother

    • Both have membrane proteins

      more similar to bacteria than the

      cells membrane

    • Both reproduce independently of cell
