BIO: Cellular Respiration

Which statement describes the electron transport chain?

This process joins 2 pyruvic acid molecules into a molecule of glucose. This process converts pyruvic acid to acetyl CoA. This process splits glucose in half and produces 2 ATPs for each glucose. This process produces some ATP and carbon dioxide in the mitochondrion. This process uses energy captured from electrons flowing to oxygen to produce most of the ATPs in cellular respiration. d b/c In the electron transport chain, electrons move from one electron carrier to another, eventually reaching oxygen. The released energy is used to make ATPs.

Which statement describes the citric acid cycle?

This process produces some ATP and carbon dioxide in the mitochondrion. This process converts pyruvic acid to acetyl x CoA. This process joins 2 pyruvic acid molecules into a molecule of glucose. This process uses energy captured from electrons flowing to oxygen to produce most of the ATPs in cellular respiration. This process splits glucose in half and produces 2 ATPs for each glucose. a b/c The citric acid cycle breaks down carbon molecules, releasing carbon dioxide and forming some ATP

What is the correct general equation for cellular respiration? What is the correct general equation for cellular respiration?

6 O2 + 6 H2O + ATP energy → C6H12O6 + 6 CO2 6 CO2 + 6 H2O + ATP energy → C6H12O6 + 6 O2 C6H12O6 + 6 H2O → 6 CO2 + 6 O2 + ATP energy C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + ATP energy C6H12O6 + 6 CO2 → 6 O2 + 6 H2O + ATP energy d b/c cellular respiration extracts energy from glucose (C6H12O6) to produce smaller energy packets (ATP)

Which statement describes glycolysis?

This process produces some ATP and carbon dioxide in the mitochondrion. This process uses energy captured from electrons flowing to oxygen to produce most of the ATPs in cellular respiration. This process converts pyruvic acid to acetyl CoA. This process splits glucose in half and produces 2 ATPs for each glucose. This process joins 2 pyruvic acid molecules into a molecule of glucose. d b/c In glycolysis, glucose is split into two molecules of pyruvic acid. The released energy is stored in ATP and the electron carrier NADH.

Select the correct sequence of steps as energy is extracted from glucose during cellular respiration.
