Lab #3

Question 1

Respiration (4)

Answer 1

• the process whereby, in the mitchindria of living cells, glucose is broken down in the presence of O2 to provide energy necessary to produce ATP

(ATP used to drive all energy-requiring processes in the organism)

• in Mitochondria
• breaks down glucose
• in presence of O2
• provides energy for ATP

Question 2

Respiration: Exergonic Reaction

Answer 2

• energy is released in reaction

• respiration, as well as other metabolic processes of the plant, is under the control of enzymes (protein catalysts) which are highly specific; that is, each enzyme caralyses only one chemical reaction (or one group of closely related reactions)

Question 3

Outcome for Respiration:

Answer 3

Both ATP and CO2

Question 4

1. Dextrose
2. Starch

Answer 4

1. Dextrose
