In which part of the body are you most likely to find cells with a structure that allows a highly efficient exchange of molecules

• brain

• small intestine

• heart

• pancreas

ATP, the molecule that fuels chemical reactions, stands for

• adenine triphosphate

• adenosine triphosphate

• alanine tetraphosphide

• adenosine triphosphide

Which of the following best describes the term 'metabolism'

• the sum of physical and chemical processes that occur in an organism and are needed to sustain life

• all the chemical reactions that occur in an animal's body

• the total of the physical and chemical processes that occur within an animal's body that allow matter to be broken down

• the process of cellular respiration that occurs within the cells of plants or animals

photosynthesis is called an anabolic process because

•           pants need to make organic compounds such as glucose.

• animals need chemical energy for growth and movement

• it involves the manufacturing of a complex compound from simple ones.

• respiration breaks down complex compounds to provide the energy for both                      plants and animals.

inhibitors slow the rate of enzyme reactions by:

• (a)             blocking the active site.

• (b)             distorting the shape of the active site.

•            both (a) and (b).

•             neither (a) or (b).

Which of the following is NOT an anatomical feature found in herbivores?

• Long, complex digestive tract

• Large, flat molars for grinding plant material

• A simple stomach

• A specialized compartment for fermentation

Which of the following adaptations is unique to omnivores?

• A long, complex digestive tract

• A simple stomach

• ncisors for cutting and tearing

• flexible jaw joint for chewing a variety of foods

How do herbivores obtain nutrients from plant material?

• Through the action of enzymes that break down cellulose

• By absorbing nutrients directly through their skin

• By swallowing large chunks of plant material whole

• By relying on gut bacteria to break down cellulose

Which type of animal has a specialized compartment in their digestive system for fermentation?

• Herbivores

• Carnivores

• Omnivores

• None of the above

What type of teeth are typically found in carnivores?

• ncisors for cutting and tearing

• Flat molars for grinding plant material

• Sharp canines for capturing and tearing prey

• Premolars for crushing and grinding food
