Multiple Choice

A farmer is experiencing a problem in growing his crops. Most of the leaves of the crops are turning yellow. Which of the following will likely result from the yellowing of the crops?

• It will decrease the production of food

• It will increase the production of the food

• The production of food will remain the same

• None of the above

Multiple Choice

A vegetable farmer wants to increase his harvest. Which of the following conditions should the farmer consider?

• The kind of soil only

• The amount of water only

• The location of the pots only

• All of the above

Multiple Choice

Which of the following does NOT happen during the light-dependent reactions of photosynthesis?

• ATP is produced

• Oxygen is produced

• Glucose is produced

• NADPH is produced

Multiple Choice

A biochemical pathway of photosynthesis in which carbon dioxide is converted into glucose using ATP and NADPH is called

• Glycolysis

• Krebs Cycle

• Light Dependent Reaction

• Light Independent Reaction (Calvin Cycle)

Multiple Choice

To perform photosynthesis, plants need oxygen, water, sunlight and chlorophyll

• Agree

• Disagree

Multiple Choice

Chlorophyll absorbs white light but it looks green light because white light consists of three primary colors: red, blue, and yellow.

• True

• False

Multiple Choice

Oxygen and carbon dioxide are gases that cycle out in the ecosystem. Which gas is important to photosynthesis?

• Oxygen

• Carbon Dioxide

• Water Vapor

• Nitrogen

Multiple Choice

To make food plants need oxygen.

• False

Multiple Choice

Sunlight is needed for photosynthesis

• True

• False

​Lahat ng animals and human ay kumakain.

​Kung ang plants ay may photosynthesis, sa human and animals ay may cellular respiration. Ito ay nangyayari sa loob ng mitchondria.

​Ang mitochondria ang pinakapinagmumulan ng ating energy o ATP.

​Ito ang nasa pagitan ng inner at outer membrane.

​Dito ginagawa ang ATP.

Match

Match the following

• It is a place where chemical reactions take place to form energy for the cell.

• This part protects the whole mitochondrion

• This is the gap between both membranes present in the

  mitochondrion.

• It has a highly impermeable layer that further filters molecules and chemicals going inside the mitochondrion

• These are folds that partially fill the matrix and greatly increase

  the surface area of the inner part of the organelle.

Kung napansin ninyo, kung ano ang kailangan natin ay syang produkto ng photosynthesis o ng mga halaman. At kung ano naman ang produkto natin ay syang kailangan ng mga halaman.

We need oxygen. Plants provide oxygen.
Plants need carbon dioxide. We provide carbon dioxide.

Multiple Choice

In Krebs Cycle, the pyruvate must first be converted into Acetyl-CoA by pyruvate dehydrogenase complex found in the mitochondria.

• True

• False

Multiple Choice

During the Electron Transport Chain, a concentration gradient forms in which hydrogen ions diffuse out of the matrix space by passing

through ATP synthase.

• True

• False

Multiple Choice

A compound that stores energy in the cells is called ________.

• ATP

• cristae

• DNA

• NADPH

Multiple Choice

In which part of the cell does respiration occur?

• vacuole

• cell wall

• chloroplast

• mitochondria

Multiple Choice

What gas is needed in order to perform respiration at the cellular level?

• oxygen

• nitrogen

• hydrogen

• carbon dioxide

Multiple Choice

What are the reactants in the equation for cellular respiration?

• water and glucose

• glucose and oxygen

• oxygen and lactic acid

• carbon dioxide and water

Multiple Choice

When cells break down food into chemical energy it undergoes three major processes, glycolysis, Krebs cycle and electron transport. Which of these processes provide the greatest number of ATP molecules?

• Glycolysis

• Krebs cycle

• Electron transport chain

Multiple Choice

How do organisms get the energy they need?

• by burning food molecules and releasing energy as heat

• by breathing oxygen into the lungs and combining it with CO2

• by using the sun's energy to break down food molecules and form chemicals

• by breaking down food molecules gradually and capturing their chemical energy

Multiple Choice

Which is NOT a stage of cellular respiration?

• Glycolysis

• Krebs cycle

• Fermentation

• Electron Transport Chain

Multiple Choice

Photosynthesis is to chloroplasts as cellular respiration is to _____

• nuclei

• cytoplasm

• chloroplast

• mitochondria

Mitochondria are membrane-
enclosed organelles distributed
through the cytoplasm of most
eukaryotic cells. Their main
function is the conversion of the
potential energy of food
molecules into ATP. (adenosine
triphosphate)

Mitochondria

OUTER
MEMBRANE

It protects the mitochondrion, and
contains specialized transport proteins
such as porin to allow free passage for
different molecules into the
intramembranous space

INNER
MEMBRANE

It has long folds and is highly
impermeable to small ions due to having
a very high content of a phospholipid
called cardiolipin.
