Question

1. Differentiate Autotrophic and heterotrophic nutrition
2. What are Bio catalyst?
3.name the internal energy reserve in plants and animals.
4. Write the equation for photosynthesis​

Answer 1

Answer:

1: Autotrophs are organisms that prepare their own food through the process of photosynthesis, whereas heterotrophs are organisms that cannot prepare their own food and depend upon autotrophs for nutrition.”

2: Biocatalysis refers to the use of living (biological) systems or their parts to speed up (catalyze) chemical reactions. In biocatalytic processes, natural catalysts, such as enzymes, perform chemical transformations on organic compounds.

3: Plants have starch as the storage carbohydrate which act as internal energy reserve. But animals have glycogen as internal energy reserve.

4:6CO2 + 6H2O → C6H12O6 + 6O2. explanation:This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

Answer 2

Answer:

1)

Autotrophic Nutrition :

• In this mode of nutrition, food is synthesised from the inorganic substances.

• For autotrophic nutrition, chlorophyll and sunlight are required.

• Food is generally prepared at day time.

. All green plants and some bacteria possess autotrophic mode of nutrition.

Heterotrophic Nutrition :

• In this mode of nutrition, food is obtained from the autotrophs or another organisms.

• For heterotrophic nutrition. chlorophyll and sunlight are not required.

• Food can be obtained any time.

. All fungi and animals possess heterotrophic mode of nutrition.

2)

A catalyst is a substance which alters to promote the reaction, and a substance especially an enzyme, that initiates or modifies the rate of a chemical reaction in a living body is termed as biocatalyst.

3)

plants : starch

animals : glycogen

4)

6CO2 + 6H2O → C6H12O6 + 6O2.

This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
