When oxygen is scarce, pyruvic acid can accumulate and is converted to carbon dioxide and ethanol which causes formation of pyruvate to yield acetaldehyde
Answer:
a, b, and d are the correct answers
Explanation:
The correct answer is: B) supply energy, primarily in the form of ATP, for the cell's work
There are two main types of metabolic reactions:
1. Catabolic reactions (catabolism) are reactions of molecule breakage-macromolecules are broken down to basic units (monomers) and energy in the form of ATP is released. Formed monomers are used for the synthesis of new molecules or are released as waste.
2. Anabolic reactions (anabolism) are reactions of synthesis or building up of the macromomolecules. Anabolic reactions require energy, which means that are endergonic process and that energy is powered by catabolic reactions.
Answer:
These are the following answers to the items:
Pinocytosis -cell engulfs molecules in cell "drinking"
Facilitated diffusion- molecules helped by protein; move insoluble molecules
across plasma membrane
Passive diffusion- molecules move in and out freely from high to low concentration
Phagocytosis- cell engulfs microorganisms in cell "eating"
Active transport- molecules "pumped" in or out from low to high concentration
Passive diffusion- oxygen, carbon dioxide
Active transport- transports sodium, potassium
Pinocytosis- transports glucose, amino acids
