Biology: Respiration

Where do plants obtain the oxygen necessary to utilize foods? from the decomposition of glucose from the atmosphere directly from products of photosynthesis from the splitting of water molecules

from the atmosphere

The first stage in the decomposition of glucose is called _______________________________.

glycolysis

anaerobic

in the absence of oxygen as gas

aerobic

in the presence of oxygen as gas

The electron transport of respiration occurs in organelles called

mitochondria

Which organelle is responsible for producing energy by the Krebs cycle?

mitochondria

assimilation

Cell activities associated with the utilization of food molecules and energy in life processes.

Plant respiration occurs: primarily at night equally night and day during night only during sunlight only

Primarily at night

___________ energy is absorbed by photosynthesis, and energy is ___________ through respiration.

Solar, Released

Lactic acid buildup during respiration is the result of: anaerobic glycolysis electron transport Krebs cycle aerobic glycolysis

anaerobic glycolysis

Chemical Bond

An energy-sharing arrangement of atoms to each other as parts of a molecule. Carbon can make four bonds with other atoms, hydrogen one bond, oxygen two bonds. Each bond is a source of energy. Rearrangement of these may store or release energy.

What are the waste products of respiration? O 2 (CH 2O) n energy H 2O CO 2 ATP

CO2 H2O

Fermentation

The stage of respiration that occurs in anaerobic conditions, such as yeast fermentation.

Photosynthesis is a ___________ reaction, and respiration is a _________________ reaction, and they cycle continuously within the plant factory.

synthesis, decomposition

Name four uses of energy produced by respiration

-Producing energy for the maintenance and repair of living structures and making new molecules. -Conduction of nerve impulses in animals and people. -Production of light in bioluminescent organisms. -Production of heat.

Which statements apply to "food"? storage medium for energy energy released during photosynthesis absorb energy during assimilation release energy during decomposition

-Storage medium for energy -release energy during decomposition

Choose from the following list the three stages of respiration which convert food to useful energy. electron transport chain glycolysis lactic acid cycle photosynthesis Krebs cycle protein synthesis

-electron transport chain -glycolysis -Krebs cycle

What is the function(s) of ATP? stores the initial energy released by respiration provides the energy for all cytoplasmic chemical synthesis provides the energy for photosynthesis provides the energy for respiration a complex molecule from which all other organic compounds are made

-stores the initial energy released by respiration -provides the energy for all cytoplasmic chemical synthesis

(Select all that apply.) Choose from the following list the organic compounds that are manufactured within the cytoplasm. carbohydrates sugars waxes fatty acids alcohols hormones amino acids carotenoids starch nucleic acids
