What is Respiration?

• Repeat this process using fresh water with the same type of food.

• Set the food on fire and place it underneath the boiling tube until it is completely burnt

• •Use the following sum to calculate the change in temperature:

  final - starting = rise in

  temperature temperature temperature

• A series of chemical reactions in our cells where

  energy is released from food

what the picture shows

• What unit do we use when discussing the energy content of food

• The source of the energy required to regenerate ATP is the chemical energy stored in food.

• The Respiration Equation

• This equipment makes results more reliable because:

  Stirrer

  Enclosed vessel

  Oxygen supply

  Chimney

The energy produced during aerobic respiration is stored in a molecule called ATP (Adenosine triphosphate).

• false

• true

Every molecule of glucose that is “burned” in the cell produces

• 2 ATP

• 36 ATP

• 38 ATP

• 2 ADP

Function of the Cell Membrane:

• Breakdown of glucose to release energy in the

  presence of oxygen is a two step process:

• a mixture in which two or more substances are mixed evenly.

• •Cell membrane separates the components of a cell from its environment—surrounds the cell

• No idea teacher

•is the movement of small particles across a selectively permeable membrane like the cell membrane until equilibrium is reached.

• Diffusion

• Using Oxygen

• •Cell membrane helps cells maintain homeostasis—stable internal balance
