Biochem and Photosynthesis

What happens to certain nutrient molecules after they pass into the muscle cell?

• They are replicated in the nucleus.

• They are acted on by an enzyme and release the energy they contain.

• They are changed into tissues and organs in the cytoplasm.

• They enter chloroplasts where they can absorb light energy.

A solution of an enzyme normally found in the human body was added to a flask containing a solution of proteins in distilled water and then the flask was stoppered. This mixture was then maintained at a temperature of 27 degrees Celsius and a pH of 7 for 48 hours. When the mixture was analyzed the presence of amino acids was noted. The enzymatic solution most likely contained:

• Carbohydrases

• Maltases

• Lipases

• Protases

Which organic compounds are needed for the synthesis of the plasma membrane, contain a large amount of stored energy, and have been linked to cardiovascular diseases?

• Complex carbohydrates

• Saturated fats

• Simple sugars

• Polyunsaturated fats

The end product of digestion enters the cell of a vertebrae by the process of

• Absorption

• Osmosis

• Emulsification

• Egestion

Which term describes a solution with a pH of 5?

• Acidic

• Neutral

• Basic

• Colorless

Some molecules are combined to form large molecules by a life function of

• Regulation

• Excretion

• Transport

• Synthesis

Which subject is an inorganic compound?

• Water

• Glucose

• Maltase

• Insulin

Inorganic molecule required by green plants for the process of photosynthesis

• Oxygen

• Starch

• Carbon dioxide

• Glucose

Which two terms are considered to be opposite processes?

• photosynthesis and autotrophic nutrition

• Cloning and mitosis

• Digestion and synthesis

• Dynamic equilibrium and homeostasis

Some sea slugs store chloroplasts obtained from algae the have ingested. The chloroplasts continue to carry out photosynthesis within the slug. What advantage would this activity be to these sea slugs?

• The slug with chloroplasts can synthesize some of their own food.

• The slug with chloroplasts no longer needs to carry out respiration.

• The chloroplasts provide the slug with camouflage that protects them from UV radiation.

• The chloroplasts Contain enzymes that allow the slugs to digest starch.
