What do you know about photosynthesis and respiration?

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

What is the purpose of photosynthesis VCE?

Photosynthesis. Photosynthesis is an anabolic process where light energy is converted into chemical energy. This chemical energy is then stored within large organic compounds such as glucose and is derived from low energy inorganic compounds such as CO2, H2O.

What are 5 differences between photosynthesis and respiration?

Photosynthesis consists of two stages light reaction and dark reaction. Respiration consists of two stages, they are inhalation and exhalation. Photosynthesis takes place during the day only because it is dependent on light. Respiration is a continuous process and without respiration no organism can survive.

What is VCE biology?

VCE Biology is designed to give the student a better understanding of the nature of life, past and present. Units 1&2 cover how living things stay alive and maintain the continuity of life, while Units 3&4 investigate how cells maintain life and the challenges faced by life on Earth over time.

What is the respiration equation?

The chemical equation is C6H12O6 + 6O2 → 6CO2 + 6H2O (glucose + oxygen -> carbon dioxide + water).

How do you measure respiration in plants?

A `respirometer’ is described. The atmosphere inside a container is monitored by sensors for O2, CO2 and temperature, and is refreshed with air or a special gas mixture once a specified amount of O2 has been consumed by a plant tissue. The rate of respiration and respiratory quotient (RQ) are calculated.

Which is faster photosynthesis or respiration?

Well, the rate of photosynthesis is usually faster than respiration, so a plant produces more oxygen than it needs for itself.

What is more important photosynthesis or respiration?

Contrary to popular belief, Photosynthesis is more essential to life than Cellular Respiration. Not only does Photosynthesis maintain and produce the oxygen that is used by Cellular Respiration but, it also is the process that allows for new energy to become accessible to life on Earth.

Are photosynthesis and respiration the same?

Photosynthesis is a process in photoautotrophs that converts carbon dioxide into organic compounds in the presence of sunlight. Respiration is the set of metabolic reactions that take in cells of living organisms that convert nutrients like sugar into ATP (adenosine tri phosphate) and waste products.

What are the 2 main reactions of photosynthesis?

There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle.

What are stages of respiration?

Aerobic respiration is divided into three main stages: Glycolysis, Citric acid cycle and Electron transport chain. Glycolysis: Glucose ( 6 carbon atoms) is split into 2 molecules of glyceraldehyde phosphate (3 carbon each), then these are turned into pyruvate (3 carbons each). This produces 2 ATP and 2 NADH.
