Pyruvic acid converts to ____before it enters the citric acid cycle?

acetyl CoA

What enters the citric acid cycle (also called the Krebs cycle)?

acetyly CoA

ATP synthesis in both chloroplasts and mitochondria involves the process called

chemiosmosis

Which part of cellular respiration produces the most NADH?

citric acid cycle

Glycolysis

glucose --> pyruvate

Metabolic pathways common to both aerobic and anaerobic processes of sugar breakdown

glycolysis

What takes place in the cytosol (cytoplasm) of a eukaryotic cell?

glycolysis

4 steps in cellular respiration

correct sequence of stages in cellular respiration?

glycolysis, citric acid cycle, electron transport

The electron transport chain is a series of electron carrier molecules. Where are these molecules located in eukaryotic cells? Hints

inner membrane of the mitochondria

in muscle cells, fermentation produces

lactate and NAD+

Electron transport takes place in the ______.

mitochondria

In what organelle would you find acetyl CoA formation, the citric acid cycle, and the electron transport chain?

mitochondria

In cellular respiration, most ATP are produced by

oxidative phosphorylation

Final electron acceptor of cellular respiration is

oxygen

final electron acceptor of aerobic respiration is

oxygen

Human muscle cells use lactic acid fermentation to _____

produce ATP without O2

product of glycolysis

pyruvic acid

In glycolysis, ATP molecules are produced by

subrstrate level phosphylation

electrons carried via NADH and FADH2 is..

the citric acid cycle

NADH and FADH 2 are important in cellular respiration because they deliver high-energy electrons to the electron transport system. Electron transport produces _____ ATP molecule(s) per NADH molecule and _____ ATP molecules(s) perFADH 2 molecule

three; two

In electron transport, high-energy electrons "fall" to oxygen through a series of reactions. The energy released is used to _____.

transport protons into the intermembrane space of the mitochondria, where they become concentrated. They then flow back out into the the inner compartment (matrix) of the mitochodria. On the way back, protons turn ATP synthase turbines and produce ATP.

Describe glycoysis

two glucose split in half and produce 2 ATP's for each glucose

describe the electron transport chain

uses energy captured from electrons flowing to oxygen to produce most of the ATPs in cellular respiration.

The waste products of cellular respiration include ________

water & carbon dioxide
